Prop Repairs

Hi all

 

On my last trip out I managed to damage the prop on my Mariner 60 four stroke going over the bar at Christchurch, Rich will recall it well. ohmy.gifohmy.gif

 

Anyway I thought I had just burred the leading edges but as it is the quiet season, so to speak for fish, I took the prop off and took it down to Propeller Revolutions at Cobbs Quay.

 

Meet a nice guy there, not sure of his name but he had a quick look at it and sucked air through his teeth as most repair men do, all been trained that way aren't they Martin biggrin.gif , and said hmmm "might need a recon prop sir". He then showed me how one of the blades had deformed and the others were not that good either and did I notice the vibrations? Errrr No! unsure.gif

 

Anyway he is going to try to salvage it if not he does his own version of separate bush and prop so if it happens again you can get a new prop without an insert for about

I can thoroughly recommend a stainless prop, not just for performance reasons, but because they really do take the ground. One of our dive club ribs had a 90hp with st/steel prop for 10 years and dredged the bar many times without damage. On our other rib with 75hp and aluminium prop it was in the repair shop every year and more than once. So bad was the problem we always carried a plastic, blade replaceable prop and spare blades. St/steel seems expensive initially but over time it

I think that depends on where you are. Yes alu prop gets damaged much easier, but on the up side is that the damage absorbs some force, which otherwise may or may not breaks the next weakest link, ie bending the prop shaft.

 

Sandbar probably not as damaging as a solid lump of rock, for example had Paul had a s/s prop when he ran over that big lump of rock off Hengisbury with his Honda, I would have thought the repair bill a lot bigger.
