My Clymer manual does not seem to have your specs but I did see some info @ the address below that I feel will help you. Such as: 5 or 7.5 HP Sea King vs 6 HP, points .020, plugs .030 and other info. 40-45 ft lbs was the flywheel torque I saw searching this site. Searching this site will possibly give you direct info. jow

Just put a wrench on the nut and wack it a few times with a hammer. "Joking" lol

should be about 35-50 ft lbs or good and tight which ever works for you.

Got the flywheel off using a puller. Set the points but no spark. Turns out i was turning it the wrong way alm: Turning it counter clock instead of clockwise but it's a lesson learned lol. Time for new lower gear unit oil and try to clean the carb. Next question

Compression was at 60lbs #1 and 58 #2, is that to low to start?

put some gas and oil mix in a squirt bottle and give the cylinder a few shots and check it again

I got it started today along with new 92octane gas @24:1 ratio and new fuel lines. A few problems, water pump doesn't pump water and heads get hot. Also will not run at WOT, only partical throttle. quesitons

What can cause it to run only at partical throttle and not WOT?
What is the impeller number for replacement?
