Prop replacement & options R7 Surf - 380

Post by 007DT »

I have a few questions regarding replacement prop for my R7 surf 380.

I dinged up my large (main) Prop on our trailer (loading the boat). Not terribly but I do have a slight vibration particularly at lower speeds/RPM's 1,800-2,200ish. A few questions on a replacement...
1. Can you simply replace the larger prop or is it an assembly?
2. Are there options on the pitch and what are the benefits vs stock (what is the stock one?)
3. The prop hit the trailer while trying to load the boat although slightly bent the impact I feel wasn't terrible. Should I be concerned of damage beyond the prop? If so what? and any diagnostic I can do?
4. Good source for new/refurbished Props?
5. Any concerns on running the boat with the current prop (we are on vacation w/ the boat, now)

Thanks!

You can replace either the front or rear props individually. If not bent too bad, they can easily be repaired at a local prop shop or you can send them out to BBlades for repair. I'd hesitate to run it too much if you feel a noticeable vibration as that can cause further damage to the drive components.

Or, here's a couple shops that may be local to you (I have no experience with them). Google search or reach out to your local dealer/marina for a referral.

Yea never done a surf model on a trailer. Your not the only one.
It can mess the trailer up and your drive unit bad.
Get it fixed like smokes said or buy a spare then get it fixed.

Thanks for the info. I just sent the props to Pure Performance to be repaired and may consider a pitch change...

The Props were a Breeze to pull of the drive unit...
