    Raising the floor up

    My floor and runners are getting replaced this spring time. I am also removing the seats which have foam under them for flotation. In order to keep enough flotation in the boat I was thinking about raising the floor up 1-2 inches or what ever I need to. Does anyone see any issues with doing...

    Looses rpm's @ WOT

    It has done this ever since I bought the boat. Run @ WOT for a few miles then it will drop 200-300 rpm's. It doesn't do it at slower planing speeds. -Original Qjet leaked fuel on the throttle shaft so I replaced it with a Marine Edelbrock 600 CFM. -Vent hose has been replaced so I know it is...

    Damp Ski locker?

    Do these things always stay that way? I am out in Wyoming and rain in the summer time is not very common. Always parked with the bow up to drain water out. But it seems if it gets water in there the carpeting the factory put in always stays damp. It has the typical wood floor grate system...

    Trim drifts down by it self.

    How does one tell if it is in the pump or the rams? The book only said to disconnect the rams and see if they go up at the same speed, if one was faster it was the slower ram. But nothing how to check out the pump. How does one check the pump? Can the pump be repaired at home? Boat info is...

    I have a 1988 Maxum 20 foot open bow with a I/o in it. It has the typical back to back seats in the middle of the boat which will lay down to a bed if wanted. Mine are in rough shape and would like to remove them and the bases to install 2 single seats. This will open the floor up a little...

    power trim hoses

    I got a hose that's starting to fray and I figure it is probably best to replace all 4 hoses rather than having them blow out on me. My issue is I can't figure out which ones I need from iboats. It is a 88 Maxim with a 5.0 alpha one drive.

I was reading on accel's website it looks to me that coil was designed for points ignition but I have the thunderbolt electronic on my 88...

    The engine is in a 1975 25 foot cruiser, straight inboard. Does anyone know what the operating rpms of the engine should be? A buddy is buying it against my better judgement he is thrilled that the inside is nice.

    fuel vent hose problem.

    Seems when ever I am out on the boat on a hot day and you step on the fuel tank in the floor it will burp some fuel out into the water. I try to not fill the tank past 3/4 but it still seems to do this. I was looking at the hose and it has a 8-10 inch loop in it just before it exits the...

    loosing power on take off on hot days

    This happened a couple time last year on hot days. Take off and the engine starves for gas, back to idle and it will take off just fine. Chalked it up to the qjet being old, I now have a 1406 on the engine. It happened once this spring on a hotter day, tossed on a new fuel filter and it has...
