Hi everyone, I recently bought a 1984 procraft 1750 with a 84 Mercury 200 black max. I tried the boat out for a week before I bought it and it ran great.My problem is I have no owners manual or service manual for this engine and was wanting to know what things of importance I should know about this engine. Things such as recommended fuel octane, oil type, things I should replace, etc. etc. Thanks for any info on this matter.
