Sorry to bring this thread back upto the top, but I am wondering if there is anyone else on this forum (apart from Martin Stacey) that has the subject mentioned Suzuki engine?
Reason is, that I am having a few problems with mine, one is a problem for sure, and the other (I hope) is just a niggle more than anything.
When running, either hot or cold, put it into reverse, and sometimes it will stop dead. It's like the engine is turning itself off. This has only happened twice when going into forward gear, but seems to be getting more frequent when going into reverse.
I was at our local Suzuki dealer yesterday, and they confirmed that the engine was running exactly as it should be - the revs when idling are spot on, and as far as they can tell, there is not a problem. They were reluctant to alter the idle revs, since at 40hrs, the engine is still running in (?!?!?!) - they'd be more inclined to adjust it at the 80hr service mark. So, in the mean time, as I come into the marina, or come into drive the boat onto the trailer, I have no way of telling whether it's going to die on me, as I try and stop - this so far has caused some embarrasing berthing movements.....
Also, I think this is more of a niggle, but I am failing to get anywhere over 5800revs. With 1 person on board, no tide, and light fuel load, I am maxing out at just over 38knots at 5800revs. Pile 4 adults on board, full fuel, and 5800revs once more, 38knots...... The prop is the default 21" x 14" ali prop that came with the engine. Apart from Martin, is the 6200rpm mark actually possible on the boat? - my rib isn't too much heavier than the ribcraft 5.85, so I can't understand a 400rev drop.
I'm just interested to know if anyone else has had this kind of experience (or problem), and if so what the solution was, before I ask Suzuki......
