Thank you everyone for the advice! I’m loving the manual and links. Regarding the head gaskets, we could make our own by scanning the existing gaskets and cut them out with our CO2 laser cutter, assuming it would cut through the material. I’d like to try this instead of using the old gaskets we got in. The originals got torn up while taking the motors apart.
Can someone tell me what type of gasket material to buy (and maybe where to find it) for different applications such as head gaskets, intake gaskets, base gaskets, etc?
Also, here is my list of motors. I found them on marketplace over the past few months and averaged about $50 a piece:
- 1956 Evinrude 7520, 7.5hp
- 1954 Evinrude 7516 7.5hp
- 1958 Evinrude 5516, 5.5hp
- 1956 Johnson QD-17, 10hp
- 1950 Johnson QD-11 10hp (this one has a very different carb and is going to be a challenge)
- 1947 Johnson HD25, 2.5hp
- and two 1963 McCullogh 7.5hp motors (these are in better shape, but maybe more challenging since parts and information are hard to find)
