Hey I was wondering if anyone in there travels has happened across a journaled gathering of information containing everything there is to know about this motor so that I can reference it if ever I stubble across a problem? Anyone ever come across such a neatly organized document?
Meanwhile, I need to do a carb rebuild first, but this is kind of a quandary. This is a BIG boat (from my little view anyway) it's a 28' Searay with a hotel lobby in the bow. Can;t get it to plane, it will only go up to about 2700/15mph on the water. Strangely enough, on the trailer it will rev well past that, even when we ran it out of the troff vs the muffs to test the shift cable. I don't know if that's near enough pressure in order determine if the shift cable is of suspect still, but I don't think it to be. Am I wrong?
My guess is that there is a fuel supply issue. Every once in a while we will get a backfire trying to punch the hole not when starting ever though, just when great demand is put on it so I thought I could at least put timing on the back-burner. Could it run that smooth out of the water and at idle if the timing was that far out? I was gonna start with a carb rebuild, then add an electric fuel pump. I can see fuel squirt inside the venturi, but it is inconsistant, you have to crank it a few time to get the fuel pump going, THEN you can pump the throttle and see fuel. Am I right to think that even a boat this big should get up and over 18mph/2700rpm on the water?
