A few things to look at or try....do you have a new set of champion QL77JC4 ? Try a better oil preferably synthetic....I'm running mine at 75 to 1 and I know guys running 100 to 1 especially if your idling or trolling a lot. There's a service bulletin about running a little more advanced (1/4 to...
The e and the s suggest 1990....not sure if anything is different though. Either your not doing a complete carb redo or your spark is weak. I'm going with your spark. Buy one or one like this and make sure your jumping 3/8 or better and it's a nice blue arc. Inline spark testers are inferior...
All tradesman above are old school guys. Prop guy (still a hand banger) is 65.....machine shop guy is 70 and it's his grandfather's old shop and my maritime welder buddy 63.
They all said the same thing. Stainless steel wire brush.
I'm sticking with them thanks
Does your motor look like this? If so what parts do you need? Tim did me a hell of a favor and I think paying it forward would be a nice thing to do. Let me know what you need and just pay the shipping.
3 welders told me this....one a professional prop guy who is a close friend, my machine shop buddy who's an expert welder and a professional welder who works in the marine fishing industry and has 110 guys welding on his staff. No grinders.
I was told not to use a grinder on the alum....puts impurities in the metal. Stainless steel brush only.
Crosby....I might have some Merc 7.5 parts for you. Let me check and I'll get back to you.
Be interesting to try the aluminum brazing rod....I bought some at the boat show years ago to patch my aluminum boat but couldn't get it to stick. He sure makes it look easy as did the salesman at the boat show.
Might have to try it again as he said it's 2 gen rod. I know when welding aluminum...
I like the radiator people advice....drain the oil, leave out the plugs and have them slug some on. Grind/polish and paint. Easy peasy.
It's an E-Tech, she's worth it!

Tilting it is fine....and I'm 60. The problem is I have a helm in the front and I beach it a lot. Running back tripping over everything as I approach the beach is getting quite old.
What a tiny tach?
