I first need to say how fantastic this site has been, I am now in the know that much that I'm dangerous as a boat mech.
I purchased a 2013 242 Ltd S about 5 weeks ago. took it for a service and the mech that did the work was full of crap, to be honest. the Port Engine is good and happy. the Starboard engine sounds a little rough. here are what's been done to get me to this point;
1) Proper Service by Yamaha Dealer has now been done (plugs / Oil / Filters Oil) Air filters have been cleaned and are good.
2) I found a stuck open injector after the crap boat mech so I then had them serviced, the fuel is now clean and good.
3) If you start the engine on the trailer and rev it up it'll go over 4000 rpm to 7000 rpm no issue without water cooling - yes I know but I am at that point in fault finding. no temp alarm is being given.
4) Start the engine then turn on the water cooling and rev it, you'll get maybe 4000rpm max and cavitation when on the trailer, it really feels like backpressure, to be honest. is this even possible from the cooling water in an exhaust?
5) in the water same issue as point 4 above.
both pee holes have water coming out, one more than the other so I am going to check the intake crate on the right engine
As I don't get it unless I have cooling water on the trailer or while floating in the dock I can't help but think it is some kind of back pressure within the exhaust system. I am also going to look at the jet pump but as it doesn't do it when I don't have water in then it seems less likely to be this I assume. Has anyway known of this.
One last thing, after the Yamaha Dealer looked at it and when the boat is low RPM and idle RPM's it's fine. He checked the piston heights and pressures and said they are normal and within limits. the boat has around 270 hours on both engine's
thanks in advance if you've seen this and can help.
