The 4 blade max prop should be standard equipment. This is my 3rd season with it. Sails faster, motors faster at lower rpm, and nearly zero prop walk when going in reverse. This is the best upgrade that I have done to my now 40 yo boat. The safety and comfort provided by this equipment is priceless, and every boat I own in the future will have one. It preforms as good as it looks.
Had to remove transmission and just needed the replacement O-Rings for the shaft seal. Quick shipping and delivery. Always satisfied with PYI.
Successfully re compressed shaft seals by installing new locking screws. No more spraying when underway. Thank you!
HI ERIC, Yvette was my ex.
I am Pierre and yes it's perfect. Very good service.
Bought the grease and fittings (have a grease gun already)
Prop almost ready for paint and salt water!
- PYI provides pre-purchase install details
- purchase via their web-site was easy
- delivered to my door in Canada
- everything was as expected
$12.00 seems high. How about a choice using USPS’ lowest rate and slowest? I got this be cause I used up the last of my grease just now. And, the boat was launched. Did not need it till next year.
Thanks for getting these set screw packages to me so soon and a great price.
I can’t say enough about the service I received from the PYI team. Initial advice from Ben on the problem with pitch and with specs on my boat how to fix. Service with no charge to me immediately re shipping the right parts after initialing sending the wrong ones. Jerome walking me through how to change the pitch while my boat was in the slings. My boat with max prop now performs beautifully. Terry , Georgian Bay, Canada
My A model installed well and functioned great during break in period with no squeal or heavy mist. Used to replace my old brass stuffing box on a sailboat.
I wish I could remember the young man's name that assisted me in solving the problem with my prop. He was sincere, efficient and professional in resolving the issue which took a few phone calls back and forth while he did the research. He also took the time to explain to me what was needed and why. I do wish I could remember his name.... Thank you for all your assistance.
Thank you, looks great!
Unfortunately I received the grease AFTER my boat was launched. I look
Forward to using it at haul out. I only wish the shipping and duties weren’t so pricey.
Professional, accurate, fast and friendly are just a few adjectives that came to mind with my recent order. Not even 4 days passes between my initial call for information to delivery. I highly recomment PYI!
PYI’s service is always good, and the Max-Prop Grease is fine, but the plastic tube that it comes in screws into the grease gun (provided with Max-Prop grease kit) and can become stripped after several uses. This prevents using the remaining grease in the tube which can be more than 25%. The best strategy is probably to avoid removing the tube after it's screwed into the grease gun, but this might be impractical in some situations.
I should have ordered sooner rather than wait till it was almost time to launch, but I received my grease gun fast so it wasn’t a problem.
Thanks for sending this hard-to-find kit so quickly, and in good shape. Much appreciated!
Many thanks for your great service and information.
Thank you for your prompt service and follow-up.
I called to confirm the size required based on the prop invoice and whoever answered was extremely helpful and pleasant, and the order arrived promptly.
We installed this check-valve on several dripless shaft seals with good results.
