I have been watching on YouTube, Sailing Uma. They have put together a complete electric boat using an ocean volt drive a huge supply of high tech batteries
Nice job! And why wouldn't it hold? The previous one lasted 51 years!I can imagine doing the electric overhaul and/or the outboard if this fix doesn't hold.
My only experiences with an OB “Cast Iron Jib” was with my Catalina 22. Biggest problems I can recall back then (early 70’s) was cavitation in anything over 4’ and plus seas.The original Atomic 4 engine on our E29 has developed a leak in the salt water cooling system - a damaged bolt in the side plate that our mechanic doesn't dare to touch in case it renders the engine entirely useless. For now, the leak is a dribble, but we don't dare go on a summer cruise in case it turns into a gush along the way.
Called around re: repowering. The beta marine rep says about $28K to put in a new engine, and he doesn't do rebuilds any more because it's too expensive. No way we're spending that much! Got an estimate for an electric repower @ $15K. Tempting, but still this is triple our initial investment in the boat. An outboard would probably be more like $6-7K. Maybe an option. Either that, or sell to someone who likes to tinker with mechanics.
Have I missed anything?
Has anyone gone the outboard route? I wonder if this would fix my two least favorite things about the 29 -- the constant pull to port while motoring and the complete inability to steer in reverse? Or maybe it would introduce new/different problems related to weight and balance?
Thanks in advance for the collective wisdom on this board!
Unless you are cooking with propane. In that case, you have to worry about it as much as if you have an A4--which is to say, not much if your systems are properly installed and well maintained.The problem with repowering with an A4 is you still have an A4. You will get 3 to 4 times the range with the same amount of diesel as with an A4 and don't have to worry about the boat blowing up.
(These guys - using a barbell pole - actually carried the old engine up and out of the boat dockside to a waiting pickup truck like it wasn’t even there!!!)
As for A-4 parts: It’s been quite a while since I converted to diesel so am not to sure of what the parts situation truly is anymore.I suspect that "3 to 4 times the range" is over stating things by a factor of about 2.
My biggest concern with the A4 is the dependence for spare parts and knowledge on two small family businesses that may not last forever.
LOL, I actually thought of that at some point... "The engine weighs around 300 lbs. I can deadlift 300 lbs... is there a way to rig that up without breaking myself?" (Probably not.) FWIW, I have rolled the "spare" engine (still available!) around with an appliance dolly.
