No, that's wrong because you cannot buy a 1 hp marine diesel for \$350.
The formula should contain a fixed part and a variable one, like \$ = 10.000 + bhp*n.
For most small diesels the price is that of the passenger car it was designed for plus a surcharge for marine use.

"Find a manufacturer,and contact them." Doesn't work.

As most marine engines are set up for a specific boat , the tranny , exhaust style , PTO , alts, pumps, hydraulic , usually only a dealer can spec a package for you..

A 20-40 hp engine for a sail, boat might come from a mfg , the bigger commercial style stuff is dealer sold.

I would specify HP/rpm required and all the rest of your desirements and send for quotes from dealers that sell the brands you are interested in.

As it costs so much to get by the Air Police there are fewer and fewer base engines to choose from.

It just doesn't work that way.
Even similar horsepower from same manufacturer but two different engines can vary greatly. Pleasure rating versus commercial duty etc has a lot to do with it as does emissions.
As FF says there is not much to choose from especially at 3000hp, and if it's performance orientated for example then there is really only one manufacturer at 3000hp.

Actually FF it does work-obviously.Their websites and their 1-800 people can tell anyone where their dealers are.

I don't know why this guy is incapable of finding CAT,MAN,MTU etc online and needs to ask us 5 times.
