I have 88 Force on Bayliner 17'. I bought it with a nice stainless prop running 13x15. The engine seems to run great, there is a little cutting out just off idle and at idle it runs only off lower 2 cylinders (tested by pulling plug wires while idle and checking for change in rpm) but once past this spot, it runs smooth but can only reach 4000 rpm at wide open throttle and about 40 mph. I know the operating range should be 4500-5500.
I have replaced plugs, sprayed out carbs with carb cleaner, is there a fuel delivery problem? does it need fuel pump? Or rebuild the carbs? Also I have read that Force ran on only 1/2 cyclinders at low rpm to save fuel is this true or am I up in the night?
Background I bought the boat during last winter knowing it needed lots of work. I replaced flooring, carpet and all upholstery, and fixed power tilt and changed oil in lower unit. It seems to run good just won't reach operating range? Any hints, also it may have sat for a year before I got it but engine was pretty clean with very little problems.
