In the short time I've owned it, I've had a good run with my boat so far and now maybe this is the start of my woes.
I was making a 70klm trip yesterday up the coast. Approx 20klm's into the trip I struck transmission problems. I had pulled in behind an island and and was coming back out getting onto the plane moving the throttles forward and then I noticed the starboard motor wouldn't rev past 3500 rpm and there was a small but noticeable vibration. So I pulled back to low rpm and cruised to the next island (1 klm away) and went behind that island to sus out the problem. Having determined nothing was wrapped around the props/not lose/no movement/freely rotated our attention turned to the engine bay. No leaking fluids and oil fluids level fine - no alarms nothing on the smartcraft suggested any problems.
Both motors revved freely but when in gear we isolated that there was noise from the starboard transmission which was like a kchunk, kchunk, kchunk when in gear. (This is why we initially thought something was wrapped around the prop)
Anyone have any ideas what could possibly be wrong with the transmission and particularly the limitation of revs on that motor? (Spark plugs were changed 40 hours ago)
By the way I made the rest of the trip (50klm's) on one motor (sat on 2,000 rpm which averaged around 8 knots with full fuel water and 2 p.o.b.) out in the ocean and up the river to to be hauled for antifouling and polishing. After adjusting the trim tabs to compensate it drove with little yaw to my surprise.
