engine for nicholson 32

[neko]

hi folks:
the saab engine is way too small, so i wonder if you could recommend a good engine for a nic 32; also, what would be reasonable prices for such engines (new/used)?
thanks. neko

To get the correct size, work on a basis of 4hp per ton of displacement. I would guess that a Nic 32 would be around five tons displacement, so 20hp engine should be fine. As to which brand, it would depend on what deals you can get. Most modern diesels are pretty good. "Shopping around" is very cost-effective; do a lot of it.
Peter.

thanks peter;

i was wondering if you (or anybody else for that matter) recommend certain specific engines (your experience with it would be nice), their likely cost on the used market, and, maybe, point me to some web-sites or companies (tel #).

thanks again. Neko

We've recently re-engined our Rival 38 with a Beta 37.5hp and are extremly pleased with both the engine and the quality of the pre and post sales support from the company. We selected them on the basis of a similar query to yours and recommendations/testimonies from other owners.

We ordered ours at the Southampton boatshow where they were offering a deal, although I'm sure the other mfrs would do the same.

In terms of cost, we were advised to allow as much for the fitting as the engine if you are going to use a yard which we did. The estimate proved to be a good guide to the final overall cost. We had no diificulty selling our original, leaky, smokey but otherwise servicable Thorneycroft.

Regarding size, we worked on the principle of 1HP per foot which I'm sure is non-scientifc but turned out to be what both the surveyor, the prop vendors and the engine company recommended as well.

Regarding contacts www.betamarine.co.uk will find their website.

Best of luck, we certainly wish we had done it earlier.

I re-engined with an industrial Kubota which I marinised my self. Casting the water-jacketed manifold was the trickiest bit. I have since learned that there are Nanni and Beta conversions of the Kubota available here in southern Australia. I have nothing but praise for the Kubota - it starts immediately and runs sweetly. They have a very high compression ratio, even for a diesel, of 22:1. This means that they will continue to start even when a little worn and have lost some compression.
