Re: Repowering with an electric engine?

Why would a portable gasoline generator be better than a good diesel engine?

If you need a generator that shows the failing of electric drive systems currently. Diesel engines don't need a backup engine. And who wants to carry gasoline. Not to mention the additional fuel it really defeats the purpose of being green, doesn't it?

yes

you are right but just be open minded

its like the outboard versus inboard crowd

an outboard you can take off the boat carry on your shoulder and get repaired anywhere in the world

a diesel while simple tech not always so

a generator is like an outboard while it defeats the completely green scenario its simply a GAS version of a diesel electric sub

a true hybrid

a prius in a boat

so while some might cry foul at this some wont and embrace it...

a portable genny also offers countless other pros for cruising...

like the abilty to use power tools on the fly, do a quick battery charge...power a compressor etc....



in regards to who wants to carry gas, well tons of people, panga fisherman, car drivers, the list goes on

if nobody carried gas then most 99 percent of cruisers wouldnt carry dinghies...right?

Re: Repowering with an electric engine?

I carry diesel and propane. My dinghy power is electric with a solar panel on top for charging. A 3rd fuel I don't want.

Lund is the jumping off point for Desolation Sound and you don't need a steel boat to cruise there.

The electric setup was about 20lbs lighter than the next best option. The battery was the same one we would have carried to run the electronics anyway. So no weight gain from that.

And the motor was the lightest trolling motor that could get us to the 50% of hull speed as required by the racing rules. At the time the Honda 2.5 wasn't out, the lightest weight motor going was the Tohatsu 2.5 at 41lbs dry.

Instead we used a MinKota 30lb thrust trolling motor that weighed in at ~15lbs.


Again this is a very specialized setup I don't recommend for anyone outside the same situation. We had no range, no backup, no options. But for a fully crewed racing boat where there is no real intent to ever use the engine anyway it was fine.

The Honda 2hp has been around for 20ish years, but maybe that difference of 2hp vs 2.5hp was enough for you to get the 50% hull speed requirement. I have a greater than 20 year old Honda 2hp outboard for use on a dinghy.

Alex,

The current Honda 2hp weighs in at 30lbs, but it wasn't on the market at the time. I highly doubt you have a 20 year old 2hp four stroke motor. I am pretty sure no one started making them until they were mandated by the Feds.

Re: Repowering with an electric engine?

yeah they did those honda and suzuki 4 strokes with the ccs instead of actual horsepower on the cowling...

some of the first commercially made small 4 strokes...they just didnt catch on way back then

thats why you see a lot of sailors sticking to these engines dearly as they are highly desireable and RELIABLE

I also beleive they didnt have all the evap and emissions smog crap that the new 4 strokes all have and therefore lighter than an equivalent today

here is a bigger one


a 1983 7.5(this is the one I saw all the time on sailboats, a classic and standard!)

and what you are talking about, the absolute best back then(still)

Vintage 1980s Honda 4 Stroke 2HP Outboard Motor One Owner Well Maintained | eBay

new stuff has nothing on these bad boys1
