I will be fitting Shark ESC's into some of my Classic Model Power Boats this year Ronald.

Most of my power boats have "forwards only" Sea King type ESC that are excellent, but the less expensive water cooled Shark ESC will also give me a reverse function that will be handy on our smaller club lake in Southport.

I have seen other club members running with Shark ESC and they seem to work well enough and have not reported having any problems with them.

My son-in-law, Andy, has been intrigued by the person seen on YouTube who builds and runs high speed boats in a pond that appears to be the Netherlands.
Cozy RC is the name of the link. I have watched some of his videos and builds, the fella is not tied to the Shark brand. He uses Flycolor and other ESC brands.

Like I have said in previous posts I don’t use Lipo batteries or brushless motors. I like puttering around and sailing .

Hi Ron!
The Shark esc seems to be a budget friendly and fairly reliable choice. I personally like to stay with Traxxas when using Traxxas gear because of the finicky nature of Traxxas drivetrains where their esc's become "integrated" to their transmitters in many useful ways. i.e. low voltage automatic cut-off and automatic overheating shutdown.
Then we have the whole Lipo world which is a whole new animal so the learning process has been long and difficult for an old fool like me. Specialty charging systems, voltage meters and discharge rates and battery cell balance...yikes. LOL!
High speeds can be fun if you're ok with 6 minutes of run time, and constant (and I mean constant) lubrication of the flex shaft, and the inevitable need for plenty of spare props. There is an upside to that boat you've pictured is that it has an upgraded cooling jacket on the motor...super useful.
But then again, the Traxxas customer service is pretty damn good as I sent my whole Spartan Boat chassis to them and they reworked it for a nominal fee.
Despite my ramblings, I'd still give the Shark a try. Online searches on modeler sites for answers can be a huge help.
👍😉

There is a club near him and the family has a nice place on Lake Champlain, NY

Yes, vaguely looks like a fast electric. He shud find out if he has a fast-electric run site before he proceeds. Nothing worse than having a boat & nowhere to run it. Couple of MMM gents run fast electrics in a unique & specialized FE club near Alliston...we are talking 2-minute runtimes

In the early-2000s I bought several Graupner "ARTR" kits, one left...not truly a fast electric as defined nowadays, she uses a 540-brushed and 1 or 2 six-cell NiMH sticks, lasts abt 6-8 minutes so not really quick or long-lasting on the water.

Fast electrics evoke anxiety among those of us with tugs, freighters, long warships, even if he was to run clockwise round Spencer's, NPSq, MLSq. Occasionally someone runs a quick electric at Bluffers but not usually in/around the slower boats.
