What our customers are saying:
I contacted Geoff at AB Marine, he gave me a couple of alternatives, finally I decided to buy a new unit. I received the Unit from UK and last week it was installed. The engines run very smoothly WITHOUT ANY VIBRATION. I’m very satisfied with Geoff’s services and the Autoprop’s quality. Thanks again.

I frequently find others who are interested in the performance of the Autoprop and want further information about it. The most impressive inquiries are from others standing dockside when we return Silver Dolphin to her slip, stern to the dock, asking, “How does she back so well?”
-Larry C. | Tartan 3500
Just back from moving the boat 1700 nm in the med! We are so pleased with the GORI props!!! They were out performing the standard numbers under power and sail! We were seeing 8 knots with both engines at 1700rpm Calm water and sailing was awesome! Always a knot or so faster than the polars!
-Capt Scott M. | LAGOON 440
Geoff- The GORI prop set screws just arrived, less than 24 hours after speaking with you. Impressive! I’ll finish prop installation tomorrow, which will allow launch next week. Perfect. AB Marine is a first rate business. And the 3 blade folding GORI prop is the best upgrade that I made to my boat when I bought it new in 2013. Thank you.

Geoff, Variprop GP112-19” x 14 x 11 x 4 RH (cut down from the 20” dia. blade) installed and gained about ¾ to 1 knot of boat speed at same RPM as fixed blade prop and the boat stops and reverses much quicker. Very happy with results. Thanks for working with me on this and for the good advice on the props.
-Doug D. | Brewer 40 with Volvo MD 31A
Just a quick thanks for the great product and service on our Variprop GP 107-18” x 13 x 11 x 3-blade RH for our Tartan 3700 (2004) with a Yanmar 3JH3, rated at 40hp, 3800rpm, 2.62:1 ratio RH Rotation, 1.25” dia. shaft. Our Tartan 3700 arrives and leaves the dock much better than the old folding prop. This is especially useful with a new, larger boat at transient docks and mooring balls. We also see 6.5 knots at 2000 rpm in light chop; very efficient! Although sailing performance is difficult to compare as we’ve added new sails we’re seeing mid 7’s to low 8 knots in routine sailing conditions. The Variprop on our last (T 34-2) boat added over 1/4 knot and I believe that’s at least the case on the T-3700. Thanks again Geoff, for sorting out my shaft diameter mistake and getting us on the water quickly!

Hi Geoff, I wanted to let you know that we’ve sailed from the SF Bay Area to LaPaz Mexico and now we are working our way back north. We are near Ensenada Mexico. Our GORI prop has been great. We use it almost exclusively in the overdrive mode. We are getting a slight improvement in fuel utilization, but what I really like is that we can run the engine at about 2K lower RPM so it is much quieter.

Geoff. It’s Alan from Healing Over Waves aboard SV Gypsy Mare. I received the product I ordered for the Variprop. All I can emphatically say is a GREAT BIG thank you. Easy order process. Fast turnaround and all packages received without issue. Meeting you at the 2022 Fall Annapolis Boat Show was a blessing. You have alleviated our concerns with regard to how we move forward with maintaining our investment in Variprop. Have a great day.
-Popaye G. | Variprop
Everything went great on the propeller project. Thanks again for the extra help and advice today. Your tips made everything go very smoothly. I got those races loosened with solvent and then tapped the hub and they dropped right out. I did have to freeze the hub for the last one. I would’ve had a tough time without your help. Thanks again.
-Jonathan F. | Autoprop H6 RB TW BEARING Replacement Instructions
Hey Brendan, Wanted to let you know how great the props are performing. Been out last few days in light winds. 9-11 knots true. Averaged 6+ knots up wind and 5+ down. Crazy numbers for a Lagoon 400. Appreciate all the help. Have a great weekend.
-David H. | GORI 16.5 x 13 x 3 on Lagoon 400, Volvo D2-40 – 40HP – 3200RPM w/ 2.19 130S Saildrives
We had installed a Shaft Shark on our previous boat, a Malo 42 on which we circumnavigated, the unit saved the day on two occasions when we caught a line, which it promptly cut, so we’re certainly fan of the product!
