I bought my first boat a few months back. It's a 86 Bayliner Capri 19' bowrider, that came with a 92 Force 150. I have nightmares about this boat every night!
The manual tells me I should be getting 5000-5500 RPM's. But the couple of times I've had it on the water I haven't been able to get over 3200 RPM's with a max speed (confirmed by hand held GPS) of 33 mph.
Repairs done to date on this 5 hour rebuilt top end motor (according to prior owner)are:
New stator, new CDI unit (basically upgrade ignition to eliminate Converter-CD Ignition) Carbs Adjusted (but when I got it back from mechanic #1 cylinder wasn't fireing) ---Fixed with swiching #1 and #2 coils and now all seem to be fireing correctly.
repairs done by me.
New Plugs
New gaskets on the carb (which were inspected for gunk buildup from sitting)
Lower end service, and fixing the backwards installed propeller. (hopefully solves the overheating problem I get in the no wake zones)
New seals in the tilt ram that was leaking because of a missing o ring.
New marine batteries to replace the two car batteries that were in the boat.
New starter (old one had junk fall out of it when I took it apart, rebuilt one has been nothing but problems since I bought it)
New starter silinoid
I get a lot of black gunk buildup on my plug from a little use as half a tank of gas (mixed 50:1 ratio) (33 gallon fuel tank on this boat) I'm told that maybe I'm running to rich, causing the low RPM's. Is this possible?
I haven't tried starting the motor since I've gotten a new starter, but I always have the most difficult time getting this thing to start. Could this also be from the "to rich" condition that I'm being warned about?
Is there anything else that could be causing these low RPM's (other than prop) that I should be checking out before looking to go with a smaller pitched prop? (not sure what pitch prop I have now, but it may be coming off after next lake trip so I can take it to the shop to find out)
I have had this boat on the lake 3 times so far. Each time I get the same RPM's and speed even after fixing the #1 no spark problem. Compression checked out at 124-125 on all 5 cylinder before it took it's first (and last) trip to the mechanic. At WOT I hear a rattle (sounds like a bolt in a tin can) but if I back off just a hair it stops. My more experianced friend told me that the noice is a slipping prop, which is normal. Says it's because my boat can not go any faster. Could this be correct, or should I be looking for a bigger problem from the rattleing noise?
