Re: [bolger] Re: MICRO TRAWLER
- I have owned a couple of Beatles over the years. The engine was designed in the 1930's and was the cheapest engine they could come up with at the time. They sold the cars before they were built and then they didn't build the cars and Hitler used the money to build an army. In the 1930's car engines had to be rebuilt every 50,000 miles Volkswagon was no exception. What the engine had going for it was it could be dropped out for rebuilding in 15 minutes. Usually the valves were burned and new rings needed the lower end bearings and crank held up well. So in a day or so she was back on the road again and that was OK for a car. In a boat its quite a job to get the engine out for a top end rebuild. A blower will be needed to keep the air cooled engine cool. The older engines need new valves to stand the heat and lack of lead lubrication provided by leaded gasoline. I would think it would make a far better engine for an air boat. In this case it can be standing above the boat where it can get free air circulation.
They were good little engines in their time for the beatle and I really like them a lot. I helped a couple guys try to put one in an ultralight airplane but it was too heavy for the horsepower it delivers so we couldn't make it work. The litle Rotax engines like they use in wave runners might be a better choice. Doug

Yesterday,I have been informed that boat builders here are installing old VW Beetle Engines(after marinise)as Inboard Engine.They are not heavy,like outbards.I think this engine eliminates the weight problem of otherInboard EnginesAwaiting comments.Nezih
- True Doug, Ford FE gas truck engines had larger diameter crankshafts and cam profiles designed more for low RPM torque, compared to the equivalent car engines. Some GMC truck gassers even had exhaust valve rotators and stellite valve seats, anticipating heavier engine load demands.Your Isuzu may have had oil starvation issues if the oilpan capacity was not increased and the pickup lowered. I have a marinized 1956 Packard V8 with the oilpan capacity increased from 5 quarts to 4 gallons and an integral oil cooler built in. Most working boats of 25-30 feet and up have gone diesel but that may not be a practical option for the MT being discussed. 4 cycle outboards have been around for several years now and have a good track record even in small commercial fishboats that get hard use.
