ABC high pitch props

[dasboata]

The smaller tongue area is most of the problem with the captivation,,, work with it with out blowing your $it up you will have a smile on your face !!!

[Jamey]

Yeah I thought it was something about the tongue area. You are right. Not a drag race prop, more like a Winston cup prop. Needs a little coaxing to get going but sure is fast once it kicks into gear.

So I am not able to find a 1915 anywhere at the moment. I don't think the 1815 would be much different speed wise from the 1914. I am mighty tempted to try a 1817/17 lol

I'd try the 1914

I talked to Mr Jim on Friday and he was taking some 1915's out of the mold that day. So ose should have some back in stock next week.

[Jamey]

1914 is what I have. Thanks for the info from Jim. I'll wait on a 1915.

[oscarel]

I have 1816, 1818 and a 1918 if you want to try any.

Thanks Oscar. I ran a pack tonight with a little more stinger angle and got a new high of 62.3mph. I was hoping it would help plant the stern but definitely not. It does okay on glass but hitting my wakes I had two huge wipe outs. I will say my glue job is holding up nicely! Amazing nothing has broke yet. But anyway either I have maxed out the hull at this weight or I just have too much transom lift. I am afraid the higher pitch will be even worse.

[kfxguy]

Are you trying to get less stern lift?

[Mxkid261]

So, the higher the pitch of the prop, the more it will "lift" the stern of the boat?

no the more rake, of the blade the less lift of the transom

[Jamey]

Are you trying to get less stern lift?

I think so. Really the goal is to just go fast but keep some kind of semblance of stability. My thinking is the only way to do that is keep more hull in the water. I see only two ways to do that; add weight or remove lift where possible. I'll be the first to say I have no idea what the heck I am talking about though

[Jamey]

I don't know if that is true or not. All else equal MAYBE. But I was actually referring to the prop models that Oscarel was offering to let me borrow. These particular props do not have the rake angle that the newer styles have and seem to be known as having a lot of stern lift. Keep in mind some hulls need stern lift so it isn't necessarily a bad thing.

[dasboata]

also if you want to get rid/reduce slip go to the series with more blade area but really,,,slip can be used to turn larger pitches

[zooma]

Rake is new to me. I don't think Octura even mentions rake in their specs. Would someone explain it to me. I might like to try ABC props soon.

[Mxkid261]

From what I understand, and someone correct me if I'm wrong, the rake is the angle of the blade where it attaches to the hub of the prop. I would assume that more rake will produce a smaller thrust cone in the water since the blade has more of an rearward angle? Im sure dasboata, aka prop master will correct me Lol
