small inboards

[eng43hzt]

I want to build a small inboard work boat. I wanted to place an 18-25 horse v-twin motor. in a 16 to 20 foot boat. However i need to know how to run the shaft out. And what kind of block it is to allow the shaft to spin and not leak. Thanks!

Re: small inboards

Interesting proposition you have there...<br /><br />Have you considered a small diesel for your work boat? You my be able to find a diesel of that horsepower from a comercial lawn mower...<br />Check out some of these small diesels to give you an idea of whats out there... <br /><br />The only real problem I can think of that you may encounter is finding a transmission that will work, but keep an eye out on e-bay because some interesting marine transmissions pop up there on occasion..<br /><br /> Inboard stuffing box Here is some information on what keeps the inboard shaft sealed and how to service it...<br /><br />here's a picture of a typical shaft log and stuffing box assembly<br />

Re: small inboards

A deisel does sound good. I would sure get more hualing power out of it. I do have a one cylinder deisel out of a generator. It's about 15 hp or more. I have not come up with a idea for a trans yet though. Good point! Thanks for the idea and shaft info!
