Re: [bolger] Re: MICRO TRAWLER
- Might the difference in salinity from Alaska to the Med. aggravate the situation?

We all have different takes on things. I would say that any standard US IO is way to big for the Micro trawler. I have no general brief against IO's however. The US IO's tend to be American Iron and they are very easy to work on. Any modern outboard requires schooling to work on as well as special tools.
Many years ago I got rid of the outboard I had on my 26' Pacific Dory I used on a set net and put in a Mercruiser IO because of the ease of work, less cost and the fact I could put a PTO on the front for hydraulics and there by get rid of the engine driven hydraulic power pac I had.
I will say that you can't leave an IO in saltwater if you can't tilt it clear, same for an outboard. Works good on trailed boats.
- 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.
