So I just bought my first used boat, with a 90hp Force (1990 model). Yeah, my first boat ride....wait a minute. Idles fine, good engagement into gear. Now that its warmed up for 10minutes, I should be out here ready for a slow and steady climb to WOT? Well, i move it on up to WOT and ...well there lies the problem. I am only getting about 20-25mph tach at around 3000 rpm. Motor sounds just flat, ro high revs but doesnt spit or sputter either. Not knowing much of the previous owners, and buying from an idividual that ran it in his driveway with the hose hooked to it, I'm at a loss for where to begin? Boat is solid and well cared for, so that's not bothering me. But, if I have a $3000 problem out back then I'm going to be looking at a long winter. Absolutely any planning based suggestions that is warranted, is welcomed as I dont know boo about and outboard. Again, idles fine, sounds good when engaged, but absoultley no top end. I was expecting what other 2cycle boats I've been on in the past to do....wind out like it has a small power band in it. Not in my engine. Appreciate the help, and look forward to the journey!
