Any news on this ? Apologies if the above sounds a little condescending...just that when new guys post a post like yours...the folk trying to help or advise need to try and cover all bases with regards to your current knowledge, experience and set up.
There are many guys out there (perhaps like yourself) that have plenty of boating experience, but prop selection has never crossed their mind, or even had to. It was nearly 25 years of boating for me without it even being a second thought.
Now knowing what a difference it can make, let alone affecting the health and longevity of the engine, it’s an obsession of mine...for better or for worse.
One thing is for sure though. I can’t tell you how great it is to get a properly dialled in prop. Best thing you’ll ever do for your boat, in terms of useability, performance and efficiency. Worth every penny and consideration.
Just as an example...my wee boat gained around 9mph from standard ally, to one of the props I have. And 7mph with the one I use mostly. Added to this the much better fuel economy and all round suitability for cruising, water sports and the likes.
Would love to help you out, if you can find the time to post a few details. That’s what we are here for.
All the best, Allan.
