Mariner 60HP 2 stroke engine problem!
On our boat (sorry not a RIB but still has an engine that has a problem lol) we have a 60HP Mariner 2 stroke engine.
We put the engine in a bucket and on muffs and she starts on the turn of the key instantly and runs beautifully. You can rev her, engage gear, put her on full throttle all day without the slightest hint of a problem.
As soon as we lauch her, the engine will take a fair few turns to start up and then, when going, she will only go around 6/7 knots and she should be doing at least 25 or maybe more (guess but it is a planing profile hull and she should go pretty quick).
We have had a chap called Chris who is a genious with engine look at it and he says it could be that the high stata isn't working (spelling) or one of the reed blocks (spelling) is sticking.
The 2nd engineer for one of the lifeboats on Anglesey (he works at Dulas Powerboats) says that it is probably the high stata too.
Neither are 100% sure though.
Could it be something they are missing at all?
Chris has opened up the carburettes (spelling) and blasted them out and cleaned them and that still hasn't done the trick.
Thanks in anticipation,
