New Propeller

We first thought that the propeller hub alone could be replaced. But it turned out that the existing folding propeller on Molia was not made by Volvo, so it proved impossible at present to identify and locate a replacement part.

I must give a shout out here to FYB Marine in Falmouth, who are the official Volvo Penta Service Dealers for Cornwall, and in particular to Jerry Hobkirk there who advised on the correct specification for a new propeller. Not something I could have done.

Molia has a 19 HP Volvo Penta D1-20 engine coupled to a Volvo saildrive 130S-B. Jerry ran the propeller size calculation which takes into account the engine, the gear ratio (2.19), the waterline length (8.62m) and maximum beam (3.4m). It comes up with a 2-blade 16×10 left-hand propeller, and I had already specified that it must fold.

Apparently all the prop shafts over a certain Volvo Penta saildrive size (including the 130S-B) are the same.

I will post a photo of the new propeller here – as soon as it arrives.

Jerry is a mine of useful information and advice about these Volvo engines. All very much appreciated for an engine beginner like me!
