HELP.....
I?m new to boating and new to outboard engines.
I bought a 1986 by-liner with a force 125 on it. When I bought it at the repair shop they were selling it because owner bought a larger boat from there lot. They hooked up muffs and started and ran forward and backwards with no problem.
2 days later after buying the boat, i take it out and it starts to run hard. dock it and looked it over and the timing nut is missing? ok get a new one and time it correct. Took it back out and it seems like it is surging at wide open. docked it again checked it over and checked crabs and compression spark ,T-stat, heat sensor but the water flow is in question, unable to find anything wrong took it out again. This time when at full out around 5k and running for about 10 min the engine comes to a screaming halt and it is dead ... cranked it over a few times and will only start it only will start with throttle half open... Dock it again... Check compression and (cylinder 2 is gone) -NOTE- I didn't know anything about outboard engines at this time but I?m a quick learn -- rebuilt the engine... cylinder 2 rings were smeared on the wall and didn't leave any cuts... the way that it burned looked to be high compression on a early flame front running lean ? Or overheating -> guessing <- honed the cylinder out and new piston and rings later... checked and cleaned all gaskets water cooling looked clean but still replaced the water pump while I was working on the motor.
Started the motor this year and i had to adjust the crabs and timing again and the choke but started right up... water comes out the exhaust pipe and only lightly spays out the (power port holes). Ran this in a tub for 30 min increments and no prob... Forward and back nothing out of idle worked fine.. took it out on the water and ran just fine, because I?m in brake in I?m running double oil and kept the rpm around 1k-3500 k ,, it ran fine for 30-40 min +/- but then when docking the boat would bog out when switching from forward to backwards. ??? Also when on plain there is no water coming out of the upper (power port) holes. Is that normal?
Question 1: what would cause the bogging after 30-40 of running?
Question 2: why when on plain would the water stop coming out of the power port holes
Question 3: when coming off plain the water is poring out of the power port holes is that normal
Question 4: is there any con's to installing a (tall-tail) out of the engine before t-stat
Question 5: is there anyone that could give me a detailed description on how the water flow operation works?
Thank you in advance for any help... and suggestions
