Dropped Prop! Anyone know correct pitch for 19" Angler/ F75?

That's for a Yamaha 75 Horse Four Stroke, 2003 and newer.

Dropping a prop is no fun by the way!

Thanks gang.
 
I run a 13.5 X 15 Piranha but it on a Honda 90. http://piranha.com/
They will work with you to find the right prop. I use my 19 on a river ( or what used to be a river there is not much water in it now) if you damage a blade all you have to change is one blade. However I have never managed to damage just one blade. Replacing each blade is about $18 3 are still less than a new or rework. This does not help if you drop the prop.

We run a Honda 75 but if it helps.........

We run a heavily loaded 19 angler with a 2003 Honda 75. We started with a 4 blade aluminum 13 inch 15 pitch prop and it worked ok before we started really loading it up. The planing ability and general response at sea level was OK but we knew it would struggle at higher elevations and our increasing load at the time. I wanted to try a 13x14 but had trouble actually finding such a prop for our motor. So....

We switched to an aluminum 4 blade 13.25 inch 13 pitch prop last summer thinking the increase in diameter would compensate some for the 2 digit pitch drop.

It has been working great and is now our main prop. We lost about 2.5mph of top speed but the planing is now more effortless, responsiveness to throttle changes, more immediate, and our cruising speed of 14-16 knots still keep the RPM well under 5k.

We run the boat about as heavy as your average 22 cruiser but have a little less hull to push.

Likely a 13P. maybe a 15p with light load . What was the full throttle RPMs before the unfortunate event ? .
Cant compare props from other brands without knowing gear ratios .
We have seen enough composite props [like Pirhanas] break blades for no apparent reason that we do not recommend them other than an emergency spare and still would rather see aluminum cause they are more efficient .

Marc,
Is this true in the lower horsepower motors (under 100HP). I found the performance to be a little better with the composite but it is also a little bigger in Dia. Also I would have to compare it with a new aluminum prop. which for me seen to attract the bottom. However the main reason I use a Piranha prop is because they do not cost as much to repair.
By the way you sold TOGO to the person I bough her from thanks.

The composite props flex more than the aluminum, which flex more than the SS. On my Cat I run SS--higher speed, and unlikely to hit bottom. The C Dory Aluminum. I had a composite prop, and did not like it. Had a blade break in a condition where an aluminum would have survived, perhaps with a little "ding"… Dings can be easily filed out. With one blade gone, you really have to change out that blade "now". just my experience. The composite was an experiment, and back up.
 
We just ran twin Pro-pulse props 1200 miles (6 weeks of displacement cruising) up the inside passage without problems. Bought them as backups on Defender for $20 but found that our low end mpg was better.
 
Thank you!
 
I'm not sure what a dropped prop is, but I can imagine the feeling when the prop pooped.

Can't you have the prop rebuilt? I took out the stainless prop on Journey On and it was a lot cheaper to have a shop repair it. For the same price they would repitch it. It was a good job and I've been running it for a couple of years. I've also had the hub go out on Vancouver Isle and that was an easy repair.

I'm down at the south end of of the country but I'm sure there are good prop shops up north, such as the Prop Shop.

It means Poseidon owns your prop forever :smilep
