I do have a beautiful 15 hp 4 stroke Honda outboard that has been converted to run a hydraulic pump inboard. I converted it many years ago to power my sternwheeler but ended up with an antique engine. The engine is stripped down to a bare engine with external water pump and internal oil cooler. The problem is, it is a gas engine, and that is a big NO NO or is it? If the fuel supply is outside the hull and the engine is run out of fuel before a dive, then there is no fuel at all inside the sub while it dives. An engine compartment blower fan can constantly circulate air through a duct to the outside of the sub. I know as a rule it is considered a bad idea but with careful installation it could be a very nice drive system. This would be much quieter and smoother than a diesel engine. The Honda would be very easy to remove from the escape pod if I need to escape. The Honda 4 stroke is as reliable as even a Yanmar diesel. I was bragging to a Honda mechanic one time that the Honda starts with two pulls in the spring. He said it must need a tune up LOL it should start in one pull. </div><div>Hank</div></div></div></div>_______________________________________________<br>Personal_Submersibles mailing list<br><a ymailto="mailto:Personal_Submersibles@psubs.org" href="mailto:Personal_Submersibles@psubs.org">Personal_Submersibles@psubs.org</a><br><a href="http://www.psubs.org/mailman/listinfo.cgi/personal_submersibles" target="_blank">http://www.psubs.org/mailman/listinfo.cgi/personal_submersibles</a><br><br><br></div> </div> </div> </div></div></body></html>
