Hello again everyone, I’m sitting in the house waiting for the rain to let up. Word is we got 14” in a big part of our area in the past week. I called the marina today and was tol That sandy point I beached my boat on coming in late one night is back under water.
Its going to be nice seeing the lake full again.
I’ve been sitting here planning the finishing of my rebuilding my old boat. Even have my Garmin here with me in simulation mode learning how to use the functions I haven’t been using.
Now I went and opened the manual I found online for my 1992 2 stroke 40hp Yamaha.
The outboard originally had an oil tank and pump and mixed it’s own fuel. When I got it all that had been removed. Once I got it running I’ve been using 50:1 premix ratio.
I was going through the specs in the manual and Yamaha says the pump was supposed to be using a 200:1 ratio while idling and 100:1 ratio at wide open throttle.
Does anyone have experience with older mid size Yamaha outboards?
this could explain why it doesn’t like to be idled much and things build up pretty quick when it does. By the time I idle out of a cove it’s begging for wide open throttle which clears its throat and it runs a lot smoother.
I wish it did have that oil pump set up then I could troll with it some.
Do y’all think it’s a good idea for me to play around with the ratio I’ve been mixing a little? Say half way. Instead of 50:1 try 75:1 or just change a little 60:1?
If my guess is correct it should perform better. But I don’t want to burn it up fooling around either. On the other hand if 50:1 is to heavy I’m not exactly helping it either. I understand the pumps job to automatically change the ratio to match the motors rpms. At 200:1 while trolling isn’t much lubricant IMHO. And I wouldn’t dare mix that ratio and go out and hit WOT. I hate paddling. Especially when I’m made.
Again folks I’m sitting around waiting on the rain and thinking about tweaking the boat.
I’m going to finally rebuild the front deck in the next couple of days and sat here today and decided I wanted it bigger with storage.
Suppose to have 5 straight days off dry to get it done.
If my new Minn Kota happens to get here early that deck could end up on the back burner.
Strippers (hybrid)are schooling right now.
Let me know if I should stick to the current ratio I’m using or if y’all think I might have a little room for adjustments? I looked on line and found a section that mentioned Yamaha using this ratios starting back then.
Yall keep your lines tight. Think I’ll go do dishes and surprise my wife. She knows I hate doing that more than anything else. Besides it’ll keep me from getting in deeper sitting and planning to finish the boats lay out. Lol
