Hey guys - took the boat out for the first time this season today and as the title says, she was not very responsive and I couldn't get past 2200 RPMs at WOT. To put it in perspective, at the end of last season, I had her up to near 50 hauling butt and she ran like a top. Took it out of winterization in May and changed oil/filter, fuel filter, drive lube, and replaced the trim pump. Just got around to taking her out today for the first time this season.
Took it out, water was calm, and when I got past the no-wake zone and tried to open her up, she wouldn't go past about 2200 RPMs and about 10 knots. Even though the throttle seems to go through the full range of motion, from about 3/4 to WOT, there is not change in engine whine, RPM, or speed. While at the max throttle of 2200 RPMs, all gauges seemed to read normal. Temp was about 175-180, oil pressure was 55-60, and volts were 13v. Again - just couldn't get it to open up and run like I know she can.
The boat is a 2008 Bayliner F-18 Flight with 4.3l carburated Mercruiser . When I got it back home today and put it on muffs, it idled fine, but when I put it up to about 1200 rpms, it seemed to surge every now and again to 14-1500 and then back down to 1200. Only I can think of is that the throttle cable is bad/misadjusted. In hindsight, now that I think of it, - even last season, though it did seem to go to full throttle at 4k plus RPMs, there did seem to be a little slop in the throttle lever - meaning I would have to move it a little to get it to change. I assumed that was normal, but now maybe not. Ay thoughts as to whether this could be a cable, etc? Thanks!
