Hi all,
I've got a 1986 Johnson 9.9HP Outboard motor (model# J10RCDB).
I've seen a lot of good information posted here about tweaking motors, and I'm now in need of some advice. I've purchased a TinyTach and have averaged about 5800 RPM at WOT on my boat, which is a 14' Springbok. At the time, I was moving at about 31Kmh, so said my Humminbird.
These runs were with just me in the boat, and half the time it will just be me, but the other half of the time, I'll have a passenger sitting up front. I do not have info as to what prop is on the boat now. It is however pretty beat up. I'd like to replace it, and am wondering if anyone would be able to recommend one, or if it's essential that I know first what's on there now?
Thanks for any and all information!
Best,
Mark
