Great Product - Follow the Instructions Exactly
If this product does not work for you, you did not follow the instructions to the letter. Best to review the application video prior to application. If you are having someone else do it, you must ensure they know the process and time requirements between steps. If you mess up it will not work… a big expense but saved our prop and sail drive. I purchased twice… this was our third purchase but it could not be shipped via air so returning. Ocean Supply has GREAT customer service too!!

Ridiculous waste of money
Out of all things i've invested so far into my lagoon catamaran (and it was a lot), Propspeed was probably the worst investment. I have to clean the saildrives & props every 2 weeks, and we are not sitting in a marina, but moving every couple of days and have to motor a lot at the moment due to lack of wind (unfortunately). (this is on a flexofold folding prop with SD 50 saildrives). Will probably have to haul out only for antifouling my saildrives as we want to go to Galapagos later this year, so adding another boat dollar to the propspeed costs. The image was taken after 2 weeks of cruising after last cleaning.

Prop speed product
Nj single screw inboard 20' April to Dec in slip. Hauled with no barnacles. Expensive product really hoping to get a second season out of it.

I’m agreeing with with the guy
I am agreeing with the other guy post the picture on the Prop speed nobody believes me when I tell then prop speed is not worth the money prop only works like for one month and then after that it’s trash I know because I’m a diver I clean boats underwater all the time and it looks the same every time looks bad after that Trust me, do not waste the money buying on a Scammer product likes prop speed
