silicone for gluing in the transducer is a No NO, it will absorb the sound waves.

use 2 part epoxy only... I`m pretty sure I used the white Loctite marine 2 part epoxy...:thumbsup:

Figures... I was looking for a temporary way to mount it, in case it doesn't work well. Figured that if I epoxied it, it was on for good, whether it worked there or not. Any suggestions for a temporary way to afix it for testing?
 
Crap...I bet yours does not have it. My 1800 has a black fabric sock on the forward part of the center floor locker that extends the ski locker to accommodate longer water skis. I took mine off and mounted my transducer there below on the floor. Then reattached the sock.

I'll check the dryer. That is usually where we find missing socks around here...

2 ways I believe:

clean off the silicone really good, do not damage the contact surface with chemicals.

either use vasoline heavily between the surfaces and duct tape into position.
or
place the tranducer in a plastic bag of water, seal it so it does not leak. place in desired location and duct tape into place.

the vasoline or water bag will make a nice seal, no air bubbles, so the sound waves can pass thru.


don`t forget to whiz the surface area a little smooth when you decide where to glue the puck down. clean really well and apply epoxy...
 
One thing you might not realize is that adding all that oil to the gas makes your carb mixture more LEAN because there's less gas (and more oil) going into the engine per volume of air. I know it might seem backwards, but that's really how it works. A similar scenario happens to dirt bikers all the time... the bike's running lean, better give it more oil for more protection! That ends up leaning out the mixture more... until the engine blows up. As others said, 50:1 is probably more than necessary and actually will be much safer than 30:1.

You are correct that I did not realize that. Thanks.
50:1 is also a good bit CHEAPER. :)
 
Well. Last night I actually got all 3 things on my list for this week done. I think I was almost as surprised as my wife when she came to the garage at 3:45 am and said "why are you still up?".
-Depth/fish finder installed
-LEDs in engine bay, passenger area and transom installed
-Voltage readings available

I knew it was late, but not THAT late. I had a series of wiring challenges that really drug the LED wiring out WAY longer than it should have.
If these work well the next few days, then I'll sit down and design a better wiring setup. Everything is sufficiently fused, so I'll be looking at a bus bar like the BLUE SEA SYSTEMS DualBus Plus, or maybe something like the BLUE SEA SYSTEMS ST Blade Fuse Block since some of my current fuses are blade and some are the old glass tube fuses. I'd like to have all blades so I have less spares to carry.
It is a shame that a replacement factory SD fuse block isn't available, as that would be easier.

Anyhow, I didn't actually install the voltage gauge. When I got the fish finder hooked up and turned it on I immediately saw that it displays voltage. So the voltage gauge was not needed at this point.

No pics yet of the wiring, as some of what I did is ugly.

The fish finder is mounded to the driver's cup holder via 4 bolts that pass through the cup holder. So, the only holes drilled were in the $2.50 cup holder. I expect that when budget permits I'll upgrade to the 2" depth gauge instead of the MASSIVE fish finder, so this temporary mount is the best option I could think of.

Transom. Really hard to get a good pic of the lights on in my lit garage. VERY anxious to see how they look at night in the water and if the "waterproof" 3M tape that is holding them on is really waterproof:

Sweet! Now if you could only get wireless power I would add some lighting to the Speedster. Can't bring myself to drilling a hole in it. Hence I still have no tunes blasting. The rear lights under the platform look so sweet! I've never used the lights in my boat, it'll turn into a pumpkin if it's not on the trailer and washed by 6 PM, one of these days.

If only we had listened to Mr Tesla, wireless power may be a reality by now. ;)

I won't actually have tunes "blasting". Some may think it is showing my age, but I've always had the opinion that it is obscenely rude how folks blast their music where others are forced to hear it. When I see threads with guys trying to figure out their mega-watt sound systems with subwoofers and countless speakers and amps I cringe and wonder if they only boat on secluded, private lakes, or if they just don't give a shit about the other folks around them. The radio won't get used when the engine is running, and I wanted it for the NOAA weather monitor as much as for the FM radio/SD reader/USB reader. When it is used it will be loud enough for us to hear it in the boat, but not loud enough to bother the folks around us.

I already had about 25 feet of the rope light that I ordered last year for the big boat. Post 163 of this thread shows how I used it there. It did so well... the adhesive has held strong, WAY brighter than expected... that I thought I'd give it a try as a below-the-waterline light strip on the transom. I don't have high expectations for long-term durability and don't expect it to look like the purpose built underwater puck lights that are made for transom mounting. But it should give me light to see my jet pump and for folks to get out of the water at the transom at night. I'm hoping it may look sorta cool also. :)
 
The whole idea of fixing up this boat is to get the family out on the water to get places and do things that aren't really practical in the big boat.

I want to see pics of the big boat. :)

It is a 1986 Carver 3607 ACMY.
Keep in mind that I have about the same $ in the big boat as most late model Islandia owners have in their boat. I got a smokin' deal on it. We use it as our floating Condo, as we don't have the $ for a McMansion at the lake. :)
The pics are from right before I removed the old name and renamed it "Family Circus".

Dude! That's awesome. I'd LOVE to get an older boat like that and give it an overhaul. Find one that looks rough, but has a new motor and electronics.

That's a big ass boat to have on a lake.

I got lucky. Everything worked on mine, it just needed some love on the gel coat. My prior boat was a '71 Trojan TriCabin which needed refurb. Refurbing a 14.5 foot boat is fun. Refubring a 36 foot boat is a HUGE project and more work than I was up for.
 
According to Tom at SES, the rod or main bearings failed last night.
All turned out ok, but it was a tense 30 minutes when the motor stopped at dusk right as the wind started picking up. Paddled to where the wind would push us to shore, then called BOATUS, who sent Sea Tow. Was gusting to 37 mph by the time we got back to the dock. Wasn't sure what the problem was last night . Tried to start it this morning. Ran at 1k rpm for a minute (had been idling at 1500 before) before dropping. Appears to be locked up now. Will pull jet pump to be sure it isn't causing the problems, but Tom was sure and said to send it back to be fixed.
Looks like I am cursed. :(
Also left laptop at home. Typing on the phone is a PITA.

say what???:facepalm:
 
He said it was because I'm using the oil injection pump, that I should remove the pump and run pre-mix.

what!!! many people are running the injection pump, so few choose to run premix because it is a major PITA.
maybe you should have gone with SBT, sorry to hear this one popped again... really, sorry to hear...

besides, you had injection with premix in the tank, how the hell did it fail from oil???
 
He further said that there are a variety SeaDoo bulletins suggesting that the oil injection system should no longer be used, since it was designed for non-oxygenated and non-ethanol gas. That at idle it only provides 100:1 and at full capacity only 50:1, but with the new gas blends the engines need more like 30:1.

Regardless, this sucks. I'm at the lake with my extended family today and tomorrow, and leaving for Cub Scout camp with my Son Sunday morning. So I'll be up late Saturday getting the engine ready for UPS to pick up Monday.
I never wanted to get this much practice at removing and installing the 787 engine... but at least I'm getting faster. :)

It was fine when I was running the 20:1 pre-mix. Looking back, it was getting harder to start when the tank of pre-mix got down to about 5 gallons and I added 6 gallons of straight gas to it. Idle dropped from 1500 to 1300. When I ran the gas level down some more, then added 5 more gallons of gas, idle dropped to 1200. When I started it last night on a full tank of straight gas it was only idling at 1000.
I was thinking that was attributed to just the lower oil content. Looks like it was also from the bearings starting to fail.

I mentioned to Tom that the conventional wisdom on the forum is that the oil pumps are preferred and he said that the people saying that don't know what they are talking about, as there is no way to test that the oil pump is delivering the right amount of oil at any given rpm without putting them on an oil pump dyno.

I get what he is saying... I can follow the logic.
However, I verified that the oil pump was pumping strong before I installed it, so part of me wonders if the choice to only do the top end last time was a mistake. I don't know.

Regardless, i'm still holding out hope that it is a failed jet pump bearing, as I can rebuild the pump quicker and easier than sending the engine back again, and I have a spare jet pump at home, so even if something is broken it it, I will be able to get one of them rebuilt pretty quickly. Not expecting it to be a pump problem... but hoping.

I don`t know, still a ton of ski`s running stock injection...
but on the bright side you are becoming a pro at it... myself the same with all the alignments I`ve done on ours already!:lols:

it is still only recommended to run a 40:1 ratio with good API-TC oil when premixing.

is this another free rebuild?

when the PO had our challenger, it had run 13-14 years on the stock injection, even tho the PO used premium fuel from Shell, I was never sold on Nitrogen enhanced gasoline...
for years they all have had ethanol and it`s not going away...

My yamaha didnt puke bc of gasoline quality...

good luck my friend. If I were closer I`d surely lend a hand!:cheers:

That`s an indication your carb setting were off right there somehow, or the oil pump was not adjusted correctly... oil displaces fuel. running to heavy oil concentration can be to lean for sure...

I rarely ever hear about a mikuni oil pump failure itself, broken clock spring, yes, line pull off, yes, maybe a bad shaft seal, but I`ve rarely heard someone losing an engine due to an injection pump...
