Those little Honda generators are quite amazing , very compact, quite, and they sip the gasoline. I noticed a lot of sailboat people would use them for house power instead of firing up they're onboard engines, they would set them out on the bow. </div><div> </div><div> </div><div>Brian <br><br>--- <a href="mailto:personal_submersibles@psubs.org">personal_submersibles@psubs.org</a> wrote:<br><br>From: Alan via Personal_Submersibles <<a href="mailto:personal_submersibles@psubs.org">personal_submersibles@psubs.org</a>><br>To: Personal Submersibles General Discussion <<a href="mailto:personal_submersibles@psubs.org">personal_submersibles@psubs.org</a>><br>Subject: Re: [PSUBS-MAILIST] temporary propulsion<br>Date: Sat, 22 Oct 2016 07:49:04 +1300<br><br></div><div>Hi Brian,</div><div>what happened to the high powered motors you were looking at a while back?</div><div>These motors are huge & only put out 1/3 rd horsepower.
