Torque specs for SeaHorse

[Runabout59]

I have a 59 SeaHorse 35 HP Johnson. I found that I had a blown Head Gasket. Ordered all my parts and now I need to find out the torque specs or how many lbs I need to torque them at when I put it all back together. Anyone tell me please.

18-20 ft/lbs

As you may know, start in the center and spiral outwards to achieve even torque.

Start with 10 ft/lbs, do a cycle, then 15 ft/lbs, do a cycle, then do the final 20 ft/lbs. The pattern is as important as the torque value.

I would also dress the head before reinstalling. Tape a piece of emory cloth to a piece of glass, and do figure 8s with the head until you achieve an even sanding of the head. You will be able to tell by the wear marks.

Thank You so much HighTrim. This is a work in progress for us. It was a garage kept boat.. In really good condition over all. I have replaced the impeller housing, and assembly. I am replacing the thermostat, gaskets, orings, whatever looked worn I'm replacing it. I pulled the head off to ck that and found the blown head gasket. I hope that when I get all of it replaced it will run like a sewing machine... smooth. Thanks again for your help.

Have the coils been replaced?
