You know i was looking though the service manual. Does the jet pump have anything to do with my rpm problem if so what should i do?
Your 30 minutes from me and it's a nice drive South through the orchards to come for a visit, small world sometimes. Sent you contact information as my PM box just overflows here anymore feel free to use it.
The only other thing I might recommend is adding one of these to the boat, it's a single wire attachment that installs by winding the sensor wire around the exterior of the plug wire a couple of times and securing it with electrical tape. I'm not convinced making 42mph over water you're actually losing 1000 rpm's at wot.
You can attach it right at one of the plug wires where it runs out of the MPEM box and have the display handy while you're operating the boat at wot, it will confirm accuracy of your factory RPM gauge and it also has a built in hour meter.

I had one on order :-D
I'm almost proud of you at this point. Almost... :cheers: You've really done a great job keeping after that boat and learning along the way. Now if we could only find you a new ski project...
I changed it to a solas 15/20 per the mechanic at dockside marine. He said this is the impeller i wanted dont tell me this is my problem because i already want to kick him in the ass.
Change the pitch to 15/20 is bad? If so why
I do have the original here is a pic of it its allittle dinged up as you can see. Plus a pic of the solas box. I always keep everything and my wife says im crazy what does she know anyway.
Are you saying that this impeller could damage the engine

No, I'm just looking at it from the point of view of your boat being capable of making sufficient HP to turn it at WOT. In the boat world using regular propellers we experiment all the time with different props to find the sweet spot for a boat owner's wants and needs. With just a single fixed pitch variable in a given style of prop it's an easy judgment call when WOT can't be attained, you drop the pitch an inch or two and say hello to the engine and tachometer finally reaching the rpm's needed within a reasonable time frame to get the hull up on plane.
Jet pump impellers aren't quite the educated guess that a 3 or 4 blade propeller is when considering the hull, engine and weight loads, the aftermarket installed on your boat may just not work within the engines ability to make enough power to spin it up past a certain point.
I think it's holding you back at least some amount. Not hurting the motor necessarily but not allowing the motor to reach it's potential.
I'm actually thinking of going down pitch slightly, for a better hole shot (for skiing) b/c this impeller in mine is barely adequate for me skiing with my slalom ski.
60.00 dollors for a stock impeller its worth changing just see what happens
