I had a Pulsedrive. The company is no longer in business. It had it's pluses and minuses. Prop shafts were mounted to the underside of a platform. The whole platform was trimmable - great for swimming off the back of the boat. The rooster tail was different than that produced by the Arneson. The Pulsedrive threw the water high. Each chunk of water carved up by the blades tended to stay together so you had spirals getting thrown up instead of a solid spray. My passengers were usually facing backwards underway just mesmerized. Those features could not offset the impractical application on a boat with a ton of natural stern lift. It was enjoyable up to 65 mph. Not pleasant over 70 mph or in rough water. If I had the right hull for the Pulsedrive I would have kept it.

Thank you for all the info, nobody likes to be a test mule when things don't work out right and you still have to pay big money .

Sorry but to bring you negative experience with something like a Pulse Drive onto an Arneson thread is nothing but pure idiocy. There are no comparisons to the two most evident by which one is out of business. The Pulse shares nothing in relation with an Arneson at all. I fell that most people that have had a Pulse drive regretted it yet like yourself they try to lump it with an Arneson which is totally unfair and off base to say the least. When one reads your original post they could defer that you had Arneson experience and that is certainly not the case.

I think Arneson's are awesome except for around raft ups.

Easy there Rik. The original poster made this a general surface drive thread in his second post when he mentioned #6 drives. If he had not posted that I would not have made any comments. I also did not lump the Pulsedrive in with an Arneson. Please read my post again. The Arneson is a well engineered system, far superior to the Pulsedrive. If I were building big power in a cat or stepped vee hull I would take the Arneson over anything else out there. Arneson would also be my choice it I were putting on new drives and wanted to gain top end - in a hull that would respond well to surfacing props.

We good?
