- Sir,I will make my final decision after writing the advantages and disadvantages of inboards and outboards,one by one.Bcs I received so mny comments for inboards nd outboards.Nezih----- Original Message -----From: JOHN WALLISSent: Monday, November 12, 2012 8:36 PMSubject: Re: [bolger] Re: MICRO TRAWLERHard to beat modern 4 stroke outboards (Honda, Tohatsu, etc.) for fuel economy, serviceability, power to weight ratio and reliability. Also no worries with bilge venting, through hulls and fuel tank placement. Another plus is portability to a different vessel in the future. I run a Tohatsu MFS 20 HP on a 15' Diablo and am quite happy with the quiet, reliable, powerful and efficient performance.

For what a Diesel inboard/outboard drive alone costs, the tax-man could be 'greased' for likely a decade or two...

The present day inboard outboards may have problems but there is absolutely no reason why they should be less long lived than an outboard. The leg and shafting and gears as well as bearings and seals are about the same. The engine being inboard is well protected from the weather and should last longer than one out in the salt spray and rain. If they are less dependable it is because they are flawed not due to any advantage of outboard motors over inboards. I think inboards are the reliable, the easiest to work on big alternators are easily fitted. A good diesel is infinantly rebuildable. The small volvo in my boat is almost 40 years old. It is saltwater cooled and is still running and dependable. I would say the difference could be that people don't pull the inboard outboars off and have the underwater seals replaced . With the outboard that is easily done, so to me that means poor maintenance rather than more trouble prone? Doug

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

Sir,Agree with you and I will calculate the weight of Dieel Engine and also shaft angle.Maybe stern drive inboard is OK.ThanksNezih----- Original Message -----From: Mark AlbaneseSent: Sunday, November 11, 2012 9:43 PMSubject: [bolger] Re: MICRO TRAWLER
Well, sir, okay. So Hawkeye seems one half meter too long. And the photo of Katie Z is irresistible!Further, I only suggest you watch the diesel's weight and shaft angle carefully.Best o' luck.MarkOn Nov 11, 2012, at 4:24 AM, nezih wrote:Dear Mr.Mark,Thanks for your below comments.You know why I want to build MT?Bcs it lenght is less than five metric meters.In my country,boat owners,more than five meters,paying taxes.MT is capable for trailer transportation easily andit is enough for me at he moment(for 62 years old man).It is also easy to maintain it.I mean,expectations after sixty is not so high!!!Thanks againNezihNezih<1.jpg>
- 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.
