Thanks supraaddict, I thought the tps would be harder to change so Ill probably throw a new one on also. Was your problem constant or only after you've been on the water for a few hours?

Heres a couple threads I read last fall to help me Jarod.

Thanks for the info jarodag, I would have thought for sure your problem would have been the fuel pump...

Does anyone know of a cheap scan tool for these indmar assault 325 engines ? Closest dealer...

Thanks Kevin, I checked everything I could find but I didn't actually unplug and replug the connections so I'll try that. The boat is still in storage but I should have it out in a couple months at...

I have a 2006 Supra 20ssv inboard with a 325 assault engine and around 250 hours. Mid season last summer I was pulling a rider and crossed another huge wake at speed, almost immediately the boat pops...

Just checked today and this is exactly what happened, ordered the part today :)

My speedos are out too. Haven't checked the paddle wheel but I hope this is all that's wrong with mine. Thanks for the thread!

I kinda always wondered why they never did something like this from the factory. I mean it hasn't hurt anything over the past years, what's it gonna do being stuck in there for another decade?

My 2006 must have this also. I noticed years ago the floor was squishy under the front ballast bag and never gave much thought to it. I hope it can't cause any problems because I really don't have...

Found the fuse in the back of the head unit, fixed everything up! The alternator is getting the diodes replaced and should be good to go by tomorrow. Overall not nearly as bad as I had expected,...

It actually never sparked when I hooked it up backwards so I didn't notice until after I tried to start it and all I heard was a spinning noise like the starter wasn't engaging. I figured the new...

Well long story short, never trust the little red throw away cap. My new battery had the red cap on the negative. anyways I tried starting the engine before figuring it out. After switching the...

no one else has had this problem?

I have a 06 20ssv with a new problem. Once the boat reaches about 35 mph it starts surging, the more throttle, the harder the surge. The boat will go up to about 35 then cut all power until it gets...

My hoses were switched from the factory. As in the drain was on top and fill was on bottom, if that's the case, just switch them around
