Hi everyone
Earlier this year i bought a used boat with this engine.
I have some experience with boats, but not outboards.
I kinda feel like it's not running at it should.
I mounted Bluetooth smartcraft to get more than rpm tach info.
Running a little rough on idle between 800-900rpm cold and warm, sometimes 1000.
iac valve is changed.
Max 5000 rpm WOT, last owner meant he got more. I have a 10 1/18 x 15 prop. The boat is around 600-650kg with engine, 17 feet.
Oil pressure on smartcraft is around 396 kPa, which sound high for me?
The engine had service with dealer end of last season, but i changed sparks, fuel filter and hoses, iac valve, gear oil and water pump this summer too. Sparks was a little wet, i think i have some photos. There is spark on all.
Also some transparent exhaust smoke, mostly in idle.
What do you guys think?
Thanks!
