Gearbox choice

[doug748]

I am looking at the Beta 13.5hp engine which is listed as having three gearbox options:
1) Technodrive
2) PRM (extra 50 quid)
3) Hurth (extra 100) - all mechanical
What does the team think about the best bet?

Depends whether you want your prop to freewheel? which I'm told it does with the PRM, not with the Hurth. Don't know about the Technodrive. HTH T.W.

I've got the Technodrive. It seems fine. You fill it with the same oil as goes in the engine which save a bit of complication.

I like the Technodrive. The Hurth also has a great reputation as long as you dont mind that its a bit clunky.

Success

Have a look at the Vega Owners site at <A target="_blank" HREF=http://www.albinvega.co.uk/>http://www.albinvega.co.uk/</A> as they use this eengine as a standard replacement.

Re: Gearbox choice:Roger

The manual for the Technodrive (supplied without oil) on my Beta 20hp says to use ATF, and failure to do so invalidates the warranty!
Brilliant engine & box!

i have the Nanni 4150 fitted with P.R.M.150.
it is reported by thr Importers ( Peachment) to be quieter & more reliable than mecanicial boxes.
it is possible ( though not tried it ) to go from full ahead to full astear ie crash the box without damage to the box.
u will req either folding / feathering prop or brake to stop the shaft turning
i am now up to 200 hrs

The PRM 150 is a Hydraulic gearbox and you can indeed go straight from forward to reverse, but not sure this is always a good idea, but this is why they generally fit them to hire boats on the Broads. (Idiot proof). About £250 cheaper is the PRM 120, which I have just purchased, being as how I don't consider myself an idiot, and can let the revs drop before I change direction. Very simple gearbox and uses engine oil. cost approx. £450.
