Thanks Spareparts,and all other contributors,

Just to clarify,are you saying that I could use my existing drive unit with an Isuzu engine?there is like a 140 hp diesel out there which I think BOWMAN in the Uk might be able to supply a heat exchanger/manifold!!

In fareness you guys in the states know alot more about these things than we do so sorry for all the questions,but I really appreciate the help!

I highly doubt that. Diesel's have been the black sheep over here since GM came out with the 5.7L back in the late 70's. It wasn't a bad engine, but people didn't understand them and ran them like a gasser and many of them suffered early deaths. Since then the diesel market has been trying hard to overcome a bad black eye. Engines like the VW TDI and the DURAMAX helped alot in changing peoples perceptions of diesels over here, but diesel technology has only been getting pursued for less than 10 years hence why most of our small diesels are euro imports.

Thanks Ferm,I know what you mean.I worked in the States for many years and all that time it was Gas engines.The new diesels here are great,I even have a 1.6 TDCI in my car and its a great engine with plenty of torque and huge MPG.These common rail diesels over here are very popular.I would find it hard to go back to a gas engine.I also have a trooper that I use with the boat and has a 3.0 Litre Diesel,Again its all about economy!

Thanks Again, Brian

To answer the question, Mercruiser offers the 1.7 Diesel, 120 hp with an Alpha 1 Gen II drive. By the year model of your boat, you don't have an Alpha drive unless its been swaped out(easy task, just takes $).

Anything bigger and they want you to use a Bravo drive. If you have to change out the drive, If have to change out the drive for anything bigger, you may want to change to a Volvo SX type drive, they fit teh same hole as a mercruiser, but are generally stronger than the Alpha.

You may be able to find an older AQ type set up, it requires a bigger hole, so at least you won't have to add transom, just cut out more, but be aware that the older diels are not as efficent in the hp size you are looking for

heres a Yanmar for you

Let us all know how it works out for you, were all interested.

BTW, a freind of mine in NC used to build comersial net boats, he configured one of his 21 ft net boats to use a converted Izusu 4 cyl engine hooked to a Kodiak jet pump, he only built one of them, he sadi teh performance was ok, it was just converting the engine that was the pain.
