We have purchased an ex-trolle
We have purchased an ex-troller with a 4-53 Detroit Diesel. Keel cooled and probably a lot of hours. The muffler was rusted out so we replaced it. The existing stack is 3.5" and we reduced it to 3" to fit the truck muffler. Now the engine heat gauge redlines in about 5 minutes. Would the restriction in the muffler cause the engine to overheat?
