![]() ![]() I happy to report that the engine is still firmly attached to the boat. In the summer of 2007 I put 1,400 water miles on the boat and 1,200 trailer miles chasing walleye/pike in Ontario and salmon on Lake Michigan. I have trailered this boat many times into N. She balanced out well and sits in the water just fine. The engine and outdrive weighed 600 lbs and the outboad and bracket weighed 400 lbs. The bracket is mounted to the transom with 6 - 1/2" stainless bolts with channel used as back up plates. The braces were through bolted to the inside of the transom plywood and then to the stringers in the area where the inboard engine was mounted. I also had stainless "Knee braces" made for the boat. I replaced the transom plywood (rot) with three pieces of 3/4" plywood epoxied together for a thickness of 2-1/4 plus a bit for the epoxy in the sandwhich. It has been 6 or 7 years now and it has been a suscessful conversion. aluminum boat from an I/O to an outboard. Get a good structural inspection and don't spare the reinforcement. I think you can be successful but you have to consider the overall impact of putting all that weight and torque way out there on the back of the boat. Lucily I bought the new boat from the dealer who sold me the new Yammi and he credited me fully for the return motor but not for the glass work or the bracket. I pulled the decking to find that the stringers were broken, primarily due to age and the huge cantilever we hung off the back of the boat. The boat ran like a scalded dog - I mean the performance was absolutely great!Īfter about a month while returning from about 50 miles offshore, I noticed the floor flexing with every pound of a wave - not good. I used the space gained under the deck for an additional fuel tank. We removed the I/O (350), glassed up and reinforced the transom, then added a bracket and a new Yammi 225. It can also be hooked up to a DC supercharger for a 0-80% boost in just 45 minutes.I did the conversion on an older 22 foot Invader that I owned years ago. ![]() The boat comes fitted with a 22kW charger for overnight recharging from a standard marina shorepower cable. In normal use, when much of the time you’ll be pottering in and out of harbour interspersed with a couple of faster hops along the coast to a favourite beach or anchorage, that should be enough for a typical day’s outing. Of course at this speed, it will chomp through the two 63kWh Kreisel batteries at a rather alarming rate, but at a more modest (but still rapid) 26 knots it’s claimed to give a range of 25nm – much the same as most bespoke electric boats.įor context, we took it out for about 40 minutes of pretty hard use, including a number of flat-out acceleration and max speed runs and returned to harbour with 63% battery charge remaining. ![]() The short answer is astonishingly well.ĭespite a 450kg weight penalty over a fully fuelled petrol boat, and five passengers, we still recorded a top speed of over 50 knots – vastly quicker than any other electric boat we’ve tested and not far off the world speed record for a production electric boat of 57.7 knots (held by a Goldfish X9 powered by a 400hp Evoy inboard). Having tested a number of other electric boats, including the foiling Candela C-8, X-Shore Eelex 8000 and Vita Lion, we were intrigued to see how well a production-built boat like the Axopar 25 adapted to battery power. ![]()
