This year is not at all a good season for problems with boats and outboards. 3 weeks ago, I got a good 16' fishing boat with low hours on it. But when I went test it for a good hour + the 5-6 first times, it ran like new. But last Friday, major problems started on my way back. Was cruisin' to about 25 MPH when suddenly the motor stopped. It started right back up and got on plane ok but after another 30 sec, It did it again. Now when I wanted to try to restart it, something seemed to force, and it did restart but it ran really rough and didn't keep an idle. SO I shut it off and came back with my 4.5HP kicker.
When I got back home I did a compression test and the motor was still warm and the readings were from top to the bottom 120-80-120. Then I opened up the head cover and I can see that the middle cylinder wall is scratched, so I presume a broken ring? And what caused that, me I blame the oil injection. I've checked the water pump and it was ok but anyways it did pee well and the water coming out was warm.
Now, used 50HP are rare to find. I am planning to get a factory service manuel and getting the parts to rebuild it myself. Is just getting oversize pistons and rigns+ all powerhead gaskets is enough or I absolutely need to get new bearrings, crankshaft seals?
And if I want to do it myself, I will delete oil injection and mix gas-oil 50/1 in the gas tank, where is the oil injection location?
Thanks for helping me!
BTW: The outboard is a Johnson 50HP 1997 J50TLEUR
