Re: Falling short of max engine RPMs

Yea, hopefully the alarm is an easy fix, just need to get in there and trace all the wiring out.

I definitely don't want to run the engine at 3k rpms all the time, and understand the speed return...

Re: Falling short of max engine RPMs

I'm fairly happy with how it's running now, so I probably will fix other more pressing things, like the fact that the low pressure/high temp alarm isn't working. I'm hoping now that it's just an...

Re: Falling short of max engine RPMs

Well thank you for the nice compliment. I suppose I can't be 100% sure that 2700 isn't correct if it's possible that they produced a run of engines that were rated differently than everything else. ...

Re: Falling short of max engine RPMs

I've checked the throttle stop before, in fact it was one of the first things I looked at, but I'm going to check it again just to be sure.

I'm not sure how the water is getting in the tank,...

Re: Falling short of max engine RPMs

UPDATE TIME!!

Well we've been going through the engine for a while now addressing issues that we see, so figured I'd post an update to this thread.

First off, I was mistaken about the "never...

Re: Falling short of max engine RPMs

I think 30% is the norm based on what I've read.. Eitherway, if the prop is slipping more, then that means the engine is turning even slower than what the tach is reading.

Re: Falling short of max engine RPMs

Haha yea, I read them all, be silly to ask for advice and then ignore it :biggrin:

I'll get it figured out and then let everyone know what the problem ended up being.

thanks again! :thumb:

Re: Falling short of max engine RPMs

Well, I know the pitch of the prop on the boat, and I have the (supposed) engine rpm. Transmission ratio is 2.1:1, so assuming a 35% prop slip I can calculate what the boat speed should be. At 2k...

Re: Falling short of max engine RPMs

Thanks for all the suggestions everyone.. I'll try to go through an answer any questions, keep in mind that we've only had the boat for a couple weeks now and have only put about 3 hours on the motor...

Re: Falling short of max engine RPMs

No blubbering or smoke at any RPMs.. though it doesn't seem to have the strongest idle, always sounds like it's going to stall if I put it in gear and leave the engine at idle (though it hasn't...

Re: Falling short of max engine RPMs

yea, I'll definitely check the tach for accuracy first.

When we were bringing the boat home after we took delivery, at one point in time the engine did lose about 300 rpms for maybe 10 seconds....

Re: Falling short of max engine RPMs

I wasn't too worried about getting 3k while underway, but even with the trans in neutral and the batteries fully charged, she'll still only turn 2700.

There's no black smoke that I've been able...

Falling short of max engine RPMs

Our boat has a westerbeke 21 in it, and according to the manual, this engine should turn 3k RPMs. Underway our boat will only come up to about 2400 RPMs, and even with no load on the engine will...
