Great engine

Mar 05, 2021

Mounted it on a Joysway Offshore Warrior, and it's a great engine, smooth and powerful.
Tried with 3S and 4S batteries, and on the 4S the boat really flew, but it was too much for the engine mount which gave up, but the boat somehow managed to keep running. The engine must have been bouncing around a lot but is as new. Fixed the mount and got it running again.
The main issue with boat engines is durability, but it's still to early to know how it fares.

good brushless update for the
HobbyKing® H2O Style 650EP Formula 1 Tunnel 620mm
they are more powerful than the original but they will not destroy
the outboard motor base.

Great boat motor

May 01, 2017

Great motor used in my 900mm pt boat with a hobbyking 50 amp esc runs very fast with S3 30c 5000mha battery and 45 mm prop may look at a S2 battery slow it down a bit.

Super motor

May 01, 2017

This is a great motor I put this in my 900mm pt boat with a hobbyking 50amp boat esc and it flys with a 45mm prop and a S3 30C 5000Mha battery may look at going down to a S2 battery just to much power but love it .
