Re: Will a 2.3 HP outboard do?

I have a 15hp Yamaha 4-stroke weighing 56kg, I just purchased a 2.5hp Yamaha 4-stroke weighing 17kg this summer that I keep in the deep locker sitting on a spring loaded outboard motor bracket that makes it a breeze to lift out of the locker. I found that we used this motor heaps more than the 15hp due to how easy it was to lift into the tender. It pushes along pretty good for short trips. We still use the 15hp if we plan to be anchored at the same place for several days and want to do some exploring. I think it was a great decision to purchase.

I think that's an interesting idea.

Keep two motors ready -- one for longer trips/stronger conditions/heavier loads, and one just for puttering around over short distances/calm weather/light loads.

Adds a bit of clutter, but on the other hand it also adds redundancy.


A small motor like that would work for 90% of my trips, which are literally 150 meters to and from my mooring. Before someone says "just row!", there are tidal streams of up to 4 knots to deal with, but in calm weather 2.5hp would be enough. And I do row it sometimes

Thanks for the advice. And congratulations for keeping your deep locker so tidy! Where, pray tell, do you keep your scuba gear, dock lines, spare dock lines, extra PFD's, spare anchors, deck cleaning gear and boat hooks ?

Look, you have davits. Thousands of people would give their eye teeth for your gear. And your choices.

Good luck.

Re: Will a 2.3 HP outboard do?

Given the choice of rowing or using a 2.5HP outboard. outboard wins.

Re: Will a 2.3 HP outboard do?

I use to have a 1993 Nissan 5hp 2 stroke that I could lift off the rail onto the dinghy. I sold that engine a couple of years ago and now considering either a 2.3 hp air cooled engine or a 3.5 hp water cooled one. I don't remember the weight of the 2 stroke Nissan, but I'm thinking if was only in the mid 40 lbs. That motor was getting to be too much trying to lift off the rail while standing in the dinghy so now considering that the 3.5 hp weights in at close to 40 lbs and the 2.3 is around 30 lbs , it would appear that the 2.3 is the way to go? Unless the 3.5 could get up on plane with just me aboard. And maybe that 2 stroke Nissan 5 hp weighted a bit more than the mid 40lbs.

And thousands of people have larger, newer, better built more seaworthy boats than I can afford. I' m just trying to figure out the best way to deal with what I own. And this forum is EXTREMELY helpful. And I am indeed thankful that I have what I have.

That Honda has no liquid refrigeration and is very noisy. Change to something like the Suzuki 4 stroke instead. I have a small 4 stroke engine (2.5 hp) after having a slightly more powerful 2 stroke engine (3.5hp) and in what regards pulling force the 4 stroke has more because it has much more torque even if it does less speed. I practically use it all time at very low RPM. Putting more RPM does not increase much speed just makes the boat drag a lot more water.

As someone said ask somebody to try a small 4st on your dinghy first but probably it will work fine even if at low speed.

Re: Will a 2.3 HP outboard do?

Re: Will a 2.3 HP outboard do?

I use a soft bottom Avon Redcrest with a 2.5hp Yamaha 4 stroke. Works great, have had up to 5 adults in it at once and we had a great time cruising around. Sips fuel and is compact/lightweight. Have also used the 2.5 on a hard bottom and an inflatable bottom and it worked even better despite the weight increases. But inevitably sold them in lieu of the lighter/more portable Redcrest.

I just wonder if 2.3hp is enough?



Sent from a stupid phone that replaces words with weird stuff.
It's entirely legal to buy and operate a 2 stroke in the US. You can't buy them new, though.

Re: Will a 2.3 HP outboard do?

Best small motor I ever owned was an air cooled Eska 1.2 HP. Not sure if it was the prop design or what, but it would push an 11 foot john boat at faster than I could walk with two 200 lb. guys in it.

Motor Weight: 13 lbs. (6 kg.)

I truly wish I hadn't sold it. It started easy every time and was the only motor I could lend out to friends and it came back still running. Didn't smoke that bad and was fairly quiet, probably due to its smaller size. I used it on all sorts of boats, including my 17' Grumman canoe. It would push all of them along at a pretty good clip.

You might also consider an electric motor. I have a MinnKota with 55 pounds of thrust that easily moves my Cat 27, let alone a dingy. It weights about 25 lbs. and with a 20 lb. 35 AH battery, you have 4-5 hours of nice quiet power. You would be amazed at how fast it pushes a dingy sized boat. And even brand new, this combo won't break the bank.

Neither of these motors are going to plane a boat, but they do provide some good power for just getting to shore and back. And they are very easy to place on the back of a boat due to their very light weight.

Was Eska not marketed by Sears at one time?

Re: Will a 2.3 HP outboard do?

From what I've read, Eska (made in Iowa) built motors for several companies including Sears under the Gamefisher name. They also made motors for Montgomery Wards and Western Auto. Cool little motors. The 3 HP was also very lightweight. Tanaka (made in Japan) also made outboards for Sears. Not sure how these compare, but I sure was impressed with my little Eska 1.2.

Another motor you might look at is the Suzuki DF2.5. Same 30 lb. weight as the Honda, but has slightly more HP, SOHC vs pushrod, a real two speed transmission vs centrifugal clutch, water cooled vs air cooled, The Suzuki is in many ways more like a larger traditional outboard, but without the weight. Whereas the Honda seems more like a grass trimmer with a propeller. The Suzuki will plane a small inflatable as lots of YouTube videos will show. Plus, you can buy one in the $700 range. But as always, people should do their own homework.

Re: Will a 2.3 HP outboard do?

Older 4-5hp Merc 2 stroke weighs ~45#, has shift F + R, is quiet and water cooled. Find a closet classic. Mine starts in 2-3 pulls after sitting all winter. Amazing little beast.
