Re: Venting a prop??
I was down the river one day when I say a boat struggling to get on plane, his engine was the same as mine and his boat was
a touch smaller.
so me being me I had to go see what was the problem with his boat struggling so much.
I asked him what prop he was using he did not have clue about props, so he just trimmed the engine up so I could see it.
so in the water I go, (not intentionally, just leaning over to be nosey and splash), so while im there soaking wet I read the side
of the prop and its a 14 inch pitch.
so I go to my boat and come back with my spare drilled 15 pitch prop ,(the one if photo above)
he looked at me like I had 2 heads when I showed him the drilled holes to improve holeshot.
he said no way was he going to be drilling his nice shiny new prop and ruin it.
so I said ok don't do it, but try this anyway and see what happens.
so back to my boat due to him having no tools at all and I come back and swap the prop over for him to try, he is still saying I am
nuts for drilling my prop and it will never work.
Off he goes and wacks on the throttle and the boat leaps out the water, he does this about 6 or 7 times then disappears down the river.
now im thinking he thinks he is stealing my prop and I go after him in my boat.
I get near him he turns and leaves me for dust and goes back to jetty.
when I get their I asked what he thought, his first words were " what size drill bit do I need to do this ".
we laughed and chated for a while then a few other boaters came over and wanted to know what and how had I fixed the
blokes boat of bad pull away.
when we both told them about the results and what I did to this old prop, a good few people were converted that day.
I saw the same fella about 2 years later and we had a quick chat, he had told a outboard technician about the results with a drilled prop
and the bloke replied " yes its true, we drill them all the time for a small fee "
I think the fella I helped thought it was my original idea and that I had invented something special to the boat industy ha ha ha .
but so many people over the years ive shown this and they could not believe the difference it can make, especially if the boat is
a bit overly propped .
I have no idea who invented this idea or when, but I was shown in mid 1970's to late 70's and never forgot it.
.
some say it don't work on alloy props, oh yes it does.
it even works on composite props but I would not recommend it due to weakening the hub of a plastic type prop.
