Reply To: Evinrude Fastwin 18 HP 15032 Leaking Around Exhaust

Dave, The replacement bolts I used were all 1/4-20 x3/4″ which matched the originals in length exactly as I checked that prior to install.
Billw I assumed the nos with the asbestos would have been hard originally so never considered they would be too non-compliant to seal. I guess I could try to make one from Felpro that is a little softer to match the profile. I made need to do that anyway as one of the gaskets will likely break when I pull the exhaust cover back off.
Bob I used Phillips head for my replacement bolts because I couldn’t get a hex head and socket which was my original plan so I could check the torque. Maybe I’ll switch all the others to Phillips head and try a socket adapter and torque wrench as you suggest. Anytime I have tried using a torque wrench on a slotted bolt I always end up with a new scar!!

Thank you everyone for the great ideas and I’ll keep you posted on my results.

Jeff
