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.

What ever you decide DO NOT USE A STERNDRIVE INBOARD !!!! I/O as they are known in the
USA are the worst choice for saltwater. I made a poem about them :
I O, IO,-- it will never work you know
It will,you think
and then it sinks
Too much to go wrong. Seals ,hydraulics,electrical,linkage,gages and saltwater corrosion and electrolysis. Save your money. In my opinion ,you can't beat a 4 stroke outboard . The smallest that will give you the performance you desire. Keep it as simple as possible. The main advantage of and outboard is there in no thru - hull fittings to worry about . Most boats sink at their docks with leaking thru - hull fittings. Capt. Rocky
- 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.Message 42 of 42 , Nov 16, 2012View SourceTrue 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.
