1979 Mercury 115 HP, 6-cylinder 2 cycle outboard.
Understand I took an old 16 ft. Hydra Sports Aero Cobra 120 bass boat to rebuild. I first started the engine, and it ran but would not idle down so i thought ok it is most likely the carbs need cleaning. So, I said I would wait and do that before I take it out because I did not know how long before I got the rest repaired. I then found the trim not working and it was a bad trim pump, so I replace it and got it working. So, I proceeded to rework the boat by putting in new flooring and carpet. I removed and cleaned the fuel tank. While I had the tank out, I replaced the water hoses, recirculating pumps for the live well and the bilge pump.
Last year I put a new trim pump/motor on it and worked it up and down while check the fluid/bleeding air in the up position until it lifted and lowered correctly. It sat for almost 1 year. The trim lowered but will not raise now. Unsure how to proceed. Seen several things about the fluid type. One is to buy mercury fluid which is a oil. (just found this in manual)The manual calls for type A or AF transmission fluid. I used the mercury trim fluid before.
The engine last year would run but at a high idle. I have not been able to start it yet this year but turned it over and tried to start it. But it did not even try. So, I will have to use some starting fluid after I get some to get it to start up.
What I did last year was to retime it, clean the three carbs (which disassembly is not shown in the manual for this carb). The timing was way off to start with. Even the pointer was off. I check compression of all 6 cylinders they were at 95 psi to 100 psi and checked the firing etc. I ran good but just had problem with idle.
Any suggestion would be most appreciated. Thank you
