Serial # 6620136 Stamped as a 175hp
I've been told it's an 85, or 89- could anyone confirm?
25p Quicksilver stainless prop
1985 Champion 184
Bought the boat last summer, and it never really got to full power or rpm- most I've seen is 4200rpm or so. Now this last fall and winter it does this weird bog/surge/stutter thing when given more throttle than enough for 2000rpm. It doesn't always happen, but more often than not; sometimes it will do this malfunction, then pop right up on pad running 4000 rpm or so. In the youtube video you can see it runs fine if I keep it under 2k-rpm, but bogs and surges with more pedal applied.
I've pulled and cleaned both fuel tanks, replaced all fuel lines to the motor, and installed a new fuel filter/separator. Is it time to pull and clean the carbs, or am I looking at something more serious?
Also, any sources on a factory manual for this motor?
