    1985 20hp Johnson outboard conversion 30hp timing

    For timing advance adjustments if needs to be performed, need the Service Manual to check if states a difference in timing advance between both models, some motor manufacturers reserves the right to publish them, doesn't want boaters fingering their less HP motors when the next ones are more...

    2 Stroke Yam 40 HP Enduro.-

    Update : A good samaritan boater donated all the internal parts which are not brand new but are in excellent working shape. Now the motor is gearing forward/neutral/reverse as it should. Pic speaks for itself. The Club's boat operator have finally learned the hard way that Yam gear cases works...

    1985 20hp Johnson outboard conversion 30hp timing

    What have you done for the 20 to 30 HP conversion, does both models shares the same CC powerhead, with same carb, but surely with a carb and timing restriction going on between both 2. Usually more fuel intake needs slight more timing advance if the above applies... Happy Boating

    1986 20hp port and polished head

    You can also polish the porous piston's heads as well as the cylinder head to a smooth finger condition, that way will collect less carbon building up on them. Some folks shaves slightly at a machine shop the cylinder head to increase compression. Can increase the combo performance propping...

    Honda 7.5hp peeing issue

    You can't possibly run a motor on a bucket at slow rpm and expect to achieve a strong water pressure to pee well if suspect having some form of internal clog. WD-40, Carb Cleaner Spray cannulas works very well too. Will be more efficient to put that motor on a boat and on water, start it till...

    Fog

    Last year went for a 15 mile far away island cruise located at open sea, when returning to Terra Firme a dense fog rushed in fast over the water, could not see the island nor the coast, just the bow. Started up my GPS which has all the view points I usually boat at. Some minutes latter while...

    Mercury 9.9 idle mixture screw

    On newer motors due to EPA regulations the mixture screw is sealed with a alum/brass plug on top, to acces it must drill the plug out. Don't know if there's a spare part available. Anyway works OK without it. Happy Boating
