doing what they say cant be done

looking for some feedback on, 1st using this forum, and more importantly where to try and find a small 18 to 25 hp. "diesel" inboard outboard set up. I am rebuilding my 18 ft daysailer and I want to put in a diesel because of fuel safety issues and also reliability. boat is currently inverted in my shop and I will be coating the hull and making some minor repairs to the bottom, but will be doing some major refurbishing on the top side, at this point the time to install a motor "inboard" would be while it is under restoration. however I can't find any leads "in the USA" on diesel inboards....any Ideas anyone???

What's an "inboard outboard setup"? What's the displacement of your boat?

Where are you going to mount it? 18 to 25 hp? Have you done anything like this before?

Re: New Here, Inboard Diesel

Welcome to forum.

I can see a potential problem with lot a weight in the stern. It may be possible to fit the motor more centrally with a shaft drive, but these sort of modifications are not easy.

If its a sailboat the smallest diesel will be fine. 18-25hp is way too much for a 18 foot displacement hull.

Most crusing yachts still have an outboard for their tender with the associated petrol storage and there a few accidents attributable to this cause. The many outboard powered trailerable yachts also have a good safety record.

A second small (2hp) outboard trolling motor can be fitted with a main 4-6hp outboard and the combination would be more reliable than a single diesel.

Sorry to be so negative, but major changes like this do need some careful thought.

Good luck.

Re: New Here, Inboard Diesel

yes, I have done a lot of work, and fabricating on boats before just not a SAILboat. can rebuild the engine and such just looking for leads on buying an engine. the hull will be reinforced with carbon fiber and a "engine platform" will be installed in the bottom. as a stuffing box built in the stern and the boat will have a port and starboard rudder, this is a hobby Project but will be in permanant use when I am done. also I haven't got this site all figured out yet either so bear with me

Re: New Here, Inboard Diesel

also I have already put 800lbs on the boat in the location of the intended motor and she dropped in the water 1 inch. but performed flawlessly. by the way the engine is not intended for speed the intention is for torque to push thru waves, out board hanging on the transm wont cut it if your in a pinch with some nasty waves

Re: New Here, Inboard Diesel

If you're sure about this, I figure any small marine diesel will do. A small Beta 14hp is about 200lbs or so. Small diesels aren't exactly rare, depending where you live a good place to start may be a local marine diesel distributor/shop, they always seem to have used engines hanging around.

Re: New Here, Inboard Diesel

Outboards hanging off the transom do suffer a lack of drive in pitching conditions.
Some trailerable yachts incorporate an outboard well with the outboard sitting much further forward.
This would be much simpler modification.

I am doubtful you will be able to use much more horsepower in very rough onditions. You will end up hitting the wave face too hard and launching into the trough.

Re: New Here, Inboard Diesel

Hi,

About the smallest I have seen were small Nanni engines.

I think the smallest (1-cyl) Yanmar is quite compact.

I would pick nanni over yanmar (fresh water, 2 cylinders, more umps at lower revs)

How small is small?

b.

Re: New Here, Inboard Diesel

yea I will be severly ovrpowerd but there will be a limit stop to the throttle and it will only go so fast I am not looking to go faster into a wave only to not be "pushed" back by it. its all just a hobby anyway and no one will have one like it. lol hull speed on this thing is only 18 "mph" anyway so...
