Im currently trying desperately to get this awesome Sea King 25hp to run right. It runs phenomenal for all of about a minute at high speed and craps out. If I keep up with the primer, I'm golden.
Here is what Im working with... It is a 1961-62 Montgomery Ward "Gale" Sea King 25hp outboard, model number GG18738, serial 16X812221
I have been in contact several times and chewed the ear off Sherwood at discount marine (god bless his soul), and I have properly installed all necessary tune-up and related items... I teach auto shop in NJ, so Im pretty handy, and I am an old school type of guy that restores steam engines and hit and miss engines with my father, so we like these oldies and want to keep them going. I had intermittent to no spark when I got the motor, so a set of condensers, coils, points, wires, plugs, and a carb rebuild were all performed. It idles perfect, almost flawless. It even runs on 1/4 throttle at a decent pace. But 1/2 throttle and up seems to loose its prime and the glass bowl runs dry. So, using the old mechanic thought in me, if I pump the primer and it runs great that typically means you are loosing prime, it is a bad pump. I called up Sherwood again, and he had a new pump for me ready to go. I installed the pump last week and I found that the previous owner must have changed the pump before, as there were two different gaskets between the pump and motor. A large flat had gasket that covered the entire back of the pump, and then the small two hole flange gasket on the block. I thought that was odd. I installed the new pump with the single gasket, took it on the lake on sunday with my daughter, and we are right back to having to prime it for the duration of our ride. It actually seemed to loose its prime faster than with the old pump.
The tank and line were suspect, however, I use them religiously with a Johnson 6hp sea horse with no issues at all.
Any thoughts, help, suggestions, please feel free. Please dont tell me to junk it. This is a cool engine with a great look. I paid $25 at a garage sale and I have about $220 invested. If I wanted that 15hp mariner from the local guy, Im still about $600 ahead of the game, so I think Im still in the green. But I need a motor. The lake is way too big for my little old Johnson 6hp sea horse... Please help!
