3.5hp motor sufficient?

So once again I am feeling the urge to acquire a motor for pushing out on the flat water. Typically 3-4 rafts, pushed out on Westwater for example.

Is one of the little 3.5hp motors sufficient? If I stay in that range I save some wait and cost. I don't get reverse, but never going to use reverse on a raft rig anyway.

Thoughts?

I like my 6hp Tohatsu. There is a new one on the Medford, OR craigs list for $1339.

New Tohatsu 6

I spent the extra money to get the charging coil but you don't need it for a two hour push out. It is however, really nice on Cat trips.

3.5hp will be enough, you won't be going fast, but you will be moving forward in the wind. Make sure you get a long shaft

I use a 1978 4 hp mercury gnat piece of garbage to push our rafts. I can push 3 16 ft rafts to Jack creek on deso in about 5 to 6 hours (~5k flows) The 4 horse is more than sufficient to do the job. Not sure how it would handle the epic winds. Wish I had a 6 hp 4 stroke.

I use a short shaft and have a panther outboard motor bracket that I can lower the unit with and I use a pvc pipe for a tiller extension. Wish I had a long shaft!

As far a gas can goes. the new units are $$ but seal really well, even in the hot sun. I strap mine to the bracket I made it does not smell or leak. I've done a small can and refilled the motor, but I converted it to the tank and like that a lot more.

You don't need much gas for a small outboard. I only need about 1.5 gallons, maybe 2 gallons for the 20 something mile trip. A 4 stroke should be more efficient.

The 3.5hp units are nearly 20lbs lighter than the 6hp ones. Part of that is because they only have forward/neutral I suppose. But even at 60lbs for a 6hp that isn't bad at all.


It really is cost... I can get the 3.5hp for $300 less than the 6hp. That said, if the $300 is going to get me a big advantage then I'd go that way.


Even if, in strong winds, I'm barely moving forward that is better than me pulling on the oars and getting pushed back up river.

If you just run pods of 4 boats or less out of westy the 3.5 will be fine. On pods that are bigger or trips any longer, the extra horses and reverse would be money well spend . I bet I use reverse at least a dozen times on a cat trip.

I also agree the 3.5 would do the job. Check out the local KSL adds. I saw a 5 hp merc 4 stroke for $750. When the gnat poops out (which it should have done 30 years ago) I'll probably go for a lightly used motor and save some $$.

Here's what a 3.5 did for us on deso a few weeks ago. 11 rafts, 25 folks, 25 miles. Good times.
