Hey all, I'm back again.
I've replaced my stator, trigger, internal harness. The motor wouldn't start, so I had to set the timing.
Now the motor runs pretty well. I had it on the lake this weekend and noticed a few things.
The motor dies when it goes into gear. I assume this is an idle problem and have been adjusting it. I seem to have that fixed. What should that motor idle at while in forward? What should it idle in neutral?
I have to baby the throttle to get to wide open. I can't smoothly progress from idle to wide open. If I try, the engine gets bogged down and dies. I have to constantly play with it.
Also, when I do manage to get to WOT, the engine only spins at 2,500 rpm, without towing anything. However, if I turn the motor sharply and get it to ventilate, it spins up very high, around the proper 5,300 rpm range.
I'm thinking this might be the prop, and I've posted in another area of the forum. A helpful member said I should get a Turning Point Hustler prop with a 15 pitch. I'm currently running a 19, non-vented. I think it's a quicksilver, but am uncertain, as it came with the motor.
But before I put the money in the prop, I wanted to check with you guys and see if there might be something I'm overlooking in the motor itself. Maybe a carb rebuild? It's just not generating the power I think it ought to under load. Or is really as simple as switching the prop? If so, are there props similar to the Turning Point Hustler I should consider. The other helpful member suggested that prop because it is vented.
The boat is a '70 Thunderbird Seminole trihull. Empty, it weighs about 1,000lbs. I'm estimating that with fuel, batteries, motor, and people, we had it around 2,000 when I had it on the lake.
Thanks for all the help!
