hi,
I have been searching on information regarding the 18hp Briggs and Stratton Briggs & Stratton Vanguard Diesel Engine with Electric Start — 18 HP, 1 1/8in. x 3in. Shaft, Model# 432447-0105 for use in a 1969 Schock sailboat. I am considering use of a closed circuit system with a keel cooler mounted on the transom right beneath the waterline.I am replacing a Universal marine 12 hp which barely pushes the boat.(would it be possible to keep the radiator and just use an electric fan rather thatn the keel cooler?)Would this type of engine work even though not expressly made for a boat? Any suggestions or comments from the board would be greatly appreciated. |

Engines generate a lot of heat, it will be unbearable in a closed hull. You'll also have to do something with the exhaust, it should be water cooled, a heat blanket may get you by, but wouldn't pass Coast Gaurd regs. |

I am planning on using the same dry exhaust that my existing universal diesel uses. Do you think it will overheat if cooled by an electric fan blowing into the radiator. The engine bay is sealed and i installed two 3inch in line exhaust fans as well. My second concern is the driveshaft connection and transmission. Does a company make a transmission that would work. It currently has an old Morse. Thanks for your help |

I'm not familiar enough with your engines to help any on the coupling, I'm sure it could be worked out. A radiator won't work in a closed cabin, it will get to close to 200 degrees in there, keel cool or heat exchanger will remove the heat.If the electric fan could be ducted to exhaust the hot air, it may work. |
