Re: Volvo 200 outdrive water intake issue...
I would love to hear your reasoning on that, Don. Is it a simple mistrust or is there something I am missing?
30W oil is one of the recommended oils used on the older Volvo engines. The others varied over the years. Back then, synthetic wasn't even recommended.
In the newer drives, the material the shift cone was made from changed several times from what was used then (40+ years ago). Using synthetic may not hurt anything, but who knows. Give it a try and see if it slips or not. I know good ole 30W non synthetic engine oil works perfect. Let us know how your choice works out.
The "taper" you keep referring to is now called a cone. Volvo didn't translate to english very well back then.
Props get stuck on the prop shaft if crazy people use Eversieze on the prop in salt water. It almost guarantees the prop won't come off. I have cut off many (in pieces) to get them off.
Use grease on the prop shaft, and remove the prop and regrease yearly, it's a lot cheaper.
