Vibration from a 1 cylinder Tohatsu/Nissan/Mercury 6 HP 4-stroke?

CSY Man · 31-08-2007, 09:09

Well, today was the day my shade-tree mechanic told me my dink motor was corroded beyond repair in the lower unit.

(4 HP Evinrude...Anybody has a lower unit to lend me?)

Sooo, now it is time to pull out the check book and get a new kicker.

Found good deals on the new Tohatsu 6 HP, @ 52 lbs weigth.
(Same weight for the 4 HP, the 5 HP and the 6 HP, might as well spring for more HP for the same weight.)

What is holding me back is possible vibration from the single cylinder motor.

Does anybody out there have personal experience with these motors?

(The exact same motor is sold as either Nissan, Tohatsu or Mercury)

Do they vibrate...? How much? Annoying or acceptable?

We have a 6hp Tohatsu on our 10' inflatable. It is extremely reliable--always starts and run well. All small engines vibrate some, but we have not found the level of vibration on the Tohatsu to be annoying. Our boat easily planes with just me on board and eventually gets to plane with two on board. It is a great dink motor.

Oh, and one more question: Where do you keep it on the big boat?

I got a 3.5 hp and it has almost no vibration once the revs are just above idle. I keep it on a specially made bracket on the stern rail. A draw string cover is all it needs to keep it tidy and perhaps a padlock depending on where you are cruising.

It vibrates a lot. I just bought one for my sailboat and have been very displeased with it for vibration and that it performs just under the 4hp 2 stroke that I had on it prior.
