Hey guys,
I've got a 120hp force, not exactly sure on the year I am guessing between 89-95, but again that is just a guess. It seems to be more mercury than anything (thunderbolt ignition, lower unit, the usual force carbs though).
Currently, I am turning a 13 3/4" x22P four blade prop. Pushes the boat around 48-52MPH (I don't have a tach installed at this time, but judging by the sound it isn't really revving that high I'd guess around 4000 @WOT)
Can anyone tell me what Diameter/spline count/ pitch prop I can turn? (I'm used to early model johnsons, this is my first non OMC engine)
The tilt and trim works, but I believe it is bypassing somewhere (Running WOT, I can trim the motor up, but it stops at a certain point and won't trim any farther.) I've been told it SHOULD trim completely out of the water (if I were to hold the button long enough)
Running a compression on the engine (cold) #1 - 128lbs, #2 126lbs, #3 130lbs, and #4 130lbs) is this good compression? I wasn't sure what they came from the factory with.
Also, the engine was ran on a pontoon previously, and it has a "spacer" on the lower unit to extend the length (I assume?) can that be removed? and would it be worth the hassle of doing so?
I'm running this engine on an 84 tidecraft spitfire V15 (it's 14.75 I believe, around 800-1000lbs) It has a 6" jackplate also, it is jacked nearly all the way up due to the extension on the lower unit.
Thank you.
