Took my 1985 Rinker out this weekend and the boat ran fine for most of the day putting around the lake although I never really opened her up. Parked at a sand bar with the wife and kids for a few hours and when we left to head back for the launch the boat wouldn't plane out felt bogish. I moved everyone to the bow to shift the load off the back of the boat. Boat still was bogging down. When I eased back on the gas and gradually pushed the throtel back up she planed out and ran like a bat out of hell. When I got her home I pulled the fule filter on the carb inside was a lot of stuff that looked like sand until I rubbed it between my fingures and it basicly turned to powder.
I cleaned out the filter and replaced it haven't had boat back out yet, but do you think this was the problem? Two weeks before the boat was bogging a bit but not as bad as it did this past Saturday. Could this have been from the build up in the filter? Is there anything else I should look at?.

Yep, thats the problem,, i find it best every 2 years to give the boat a complete tune up & impeller change, every year change oil & fuel filters. dont forget to check the belts & hoses too. if you have a fuel/water seperator change it asap..

I have a 97 3.0 alpha one that is doing the same thing....If i rev the motor in neutral it revs fairly good. If the boat is in Gear it will die if i try to take off quickly. If I advance the throttle slowly i can very slowly get my boat up out of the water.....I can also smell a little gasoline, do i have the same problem? thank you in advance

Yeah I am hoping this is my problem. I bought the boat back in the spring and evry trip out on the water something happens. Everyone just sits there looking at me with the same stupid look on their face waiting for me to blow a gasket while they are floating in the middle of the lake as I work to get us back to the launch. This boat is turning me into a boat nazi.
