One of the engine head bolts on my 717 has sheared off. This is the second bolt in the last three years. Im currently reading compressions of 130 front end and 120 back end. Should i be concerned? Or when I fix this issue will this have an effect on my compression? The bolt and low compression...

Hello Everyone, I hope someone here can kindly help me? I need to know the engine emissions data for a 2011 Seadoo Speedster Boat (1 x Rotax 4-TEC supercharged 255bhp engine) Many thanks David.

Solved lowspeed vibration noise, on starboard engine. Max rpms on both barely 7000... Hello, need some help. Two issues... 230se with twin 215sc. Noticed today at lake when idiling around the outside of lake that the starboard engine was running a little rougher than right. Rpms were about 1500...

I have a 1997 Seadoo GTX with maybe 80 Hours on it. When i first got it, it ran beautifully for half a summer and then one day it just cut off. I have since changed all fluids such as oil, new gas, new spark plugs, new lanyard, new battery. The engine cranks, but never turns over. The Dashboard...

I need the info center for a 96 GSX Seadoo. I was replacing the LCD screen and when taking apart it was full of water! Totally rusted up. Will other years work? As long as it has the 787 engine...? I'm also new to this forum.

So I pulled the engine from my 1998 GTX RFI to repair a cracked lower water channel. While it is out I rebuilt the starter and am going to clean the RAVE valves. What else should I service while it is out and easy to get at everything? I can't remember if read somewhere about cleaning the...

Well I finally got my remanufactured 240 efi parts switched over from the old block and set it in place and got it fired up over this weekend and it has no beep when you turn the key on. I bought the boat last fall with the engine blowed up on the cheap. The key was missing and I had a key made...

I have a 2006 Seadoo Sportster 155 HP, single engine, non turbo. Other than knowing I need a new impeller and wear ring, the boat runs fine, and is a blast to drive. Top speed with gps is only 38mph, which is why I know I need them parts, I hope. The only other thing I have experienced is after...

Ok started my challenger whilst out of the water today whilst on the trailer hooked up the hose with out turning it on (as per the instruction manual) and after five or so seconds i got loud screeching noise?! i immediately shut it down any idea what this could be ? im in panic mode now.

So I've found someone selling a couple 2013 Seadoo GTI 130s and I'm looking for some advice as I've only worked on two stroke seadoos in the past. The ones I'm looking at are as follows: Ski #1: Has new SBT engine in it that has no hours on it. STARTS but had some electrical issue that locks...

I am second owner of a 2000 Challenger 1800, i hope to give it a little pick up during the off season any help in preparing for this ahead of time would be great. i guess i am thinking as far as small engine mod. or should i look at the pump house first. Thanks to any and all info

A few Questions?? The boat has a Single engine 210 HP Motor... better to get a Twin 155? or is this engine powerful enough? Does SE stand for options like depth finder and Transat seats The person selling the boat to me is expressing it is a SE? Is the price too High? Here is the...

So I've read some things that led me to believe that the factory chip is limited by the manufacturer. Some people are saying you can reflash this to open the full potential of the watercraft. I have a lot of questions in regard to this topic now: 1. The sites that offer the kit to perform...

Bad crank and rod bearings in my 94 SP engine, looking to buy entire lower end (preferably with pistons and cylinders). Also looking for MPEM for 2000 GTX millenium edition 951 carb engine, preferably with key but will also buy without. Thanks

Hello, i have a seadoo rxpx with 164 hours on it. The crankshaft was bad, and also changed piston rings, did a quick hone of cylinder walls, changed all of the half moon bearings, timing chain++ pretty much all of the neceassery things that is good to change, but now for the rebuilt i have some...

Finally, after 7 years of paying an arm and a leg for yearly oil changes on my 2008 Speedster 150 (4-stroke Rotax), I decided to do it myself: got all the needed equipment, except the manual calls fro 10W40, but the only closest oil I could find at the nearest (10 miles) West Marine is Pennzoil...

This started two weeks ago. The engine works fine "once in a while". But after I run it and pull back to idle, when I try to accelerate, it won't go past the 4100 rpm mark. It's like that "over-drive" never kicks in to get it up on plane. I put some water eater stuff in it yesterday...

I have a 1995 Seadoo SP. And for most of the summer it was working just fine. The current problem presented itself after the SP was partially submerged. The bilge lines which are usually secured to the side of the inside well above the waterline had detached from the side and lay low enough...

Hi, I really need your advice please. I am in the process of rebuilding my motor after a supercharger break. I had to open the engine base to clean out everything. I removed the head, and i did not make any change to the components ( cam or valve..etc ) Now i am putting everything back in place...

I have a 2001 Islandia w/Mercury 240 EFI M2. I was running for about 20-25 minutes at approximately 35 MPH when the engine just shutdown. I came to a complete stop, placed the "gear shift" in neutral and attempted to restart. Engine turned, attempted to "catch", but never fully caught. I...
