I had been scratching my head trying to figure a way to get to the four casting plugs behind the engine mounts w/o having to pull/lift motor. Finally came up with a solution that worked for me on my '97 176. Photo may be hard to decipher but this is what I did. Prepped the openings per usual with sandpaper and ran film of Permatex around inner edge. Placed new plug in block and, using an old plug and small pry bar, pressed the new plug in using engine mount for leverage. Had the old plug with concave surface facing block and levered new plug into seat. Takes some trial and error, and would be great to have smaller hands lol.

Tenacity is a virtue, well done However, wedge a smartly cut 2/4 under the exhaust manifold to take the pressure off, one can take the mount right off. ------------- "There is nothing, absolutely nothing, half so much worthwhile as messing around with boats...simply messing." River Rat to Mole |

Does this work for freeze plugs, too? ------------- _____________ “So, how was your weekend?” “Well, let me see…sun burn, stiff neck, screwed up back, assorted aches and pains….yup, my weekend was great, thanks for asking.” |

Ken, I trust Larry's intelligence to be able to figure this one out by himself. He certainly doesn't need me to confuse the issue!  ------------- /diaries/details.asp?ID=1622" rel="nofollow - 54 Atom /diaries/details.asp?ID=2179" rel="nofollow - 77 Tique 64 X55 Dunphy Keep it original, Pete < |

Good to know it's possible! I have a 10+ year old dry rubber stopper I need to replace with one behind the starter. No idea how accessible (or not) it is but surely an adventure!

just pull the starter... its two bolts and a couple of nuts for the wires. Pulling the starter will save you an hour of futzing to get the two plugs to line up correctly so you can lever the plug in using something you shouldn't pry on

| Or in the case of that one, you could utilize a proper casting plug insertion tool. That way you don't lever against anything and concern anyone.... They run about $75 online |

Maybe unhook battery 1st, then pull starter. I bet someone has done that backwards & had a few sparks! ------------- “Beer is proof that God loves us and wants us to be happy.” Ben Franklin |
