Hi. Maybe someone here knows how to convert this cuz I don't! Looking at a different boat but I do not trust the tach. Seemed to only be reading about 1/2 what it should but I dunno. So 17P prop, 1:6.1 gear ratio and GPS said 31mph at 2000rpm That seam right?

So my boat had a 80 35hp Johnson engine on it with a 10.1/4x14p prop on it and would do 28mph Now boat has a 83 50hp merc. It came with the same size prop and will still only do 28mph as it should with the same prop size. BUT im afraid to just go WOT for fear of ripping my transom off or the...

Engine has 125 compression on both cylinders, Starts easy from cold. Idles perfect and runs wot perfect, But from about 1/3rd throttle to just past half it is very rough and only hits on one cylinder. Whats it sound like to you. Carb, Reeds or maybe something else?

Hi and yeah another new guy with a question :roll: So anyway I know I should just get a different engine but been looking to trade mine for over a month and no takers. Plenty of offers to sell it outright though! Problem is I cant do that as I need to have a engine as I use the boat 4 or 5...
