Far from the first to do this but it turned out to
be more fun than I expected. My intent was to
just do the video and take them off. Ended up
leaving them on for almost a week. I need to
make up some type of a link to connect them
as there is going to be a next time.

November 16, 2021 at 3:18 pm #249774Tubs, yup that is fun for sure! Who said a three horse won’t plane a tin boat? I don’t have two threes but I have some 5.5s and a bunch of tens. I built a motor connector from a snowmobile tie rod, and I used the ball ends as well. Need some weight in the front when ya give those tens the berries. Makes me start wishing for summer already.

Boy I’ll say!! Great video! Looks like fun! I’ll try it next summer!
ScottNovember 16, 2021 at 11:05 pm #249809Running duals may cause over-revving. May consider using more oil in the fuel. I think that’s what broke the
spring on the driveshaft in my Johnson 5HP TN once.
For easier steering, tie one motor straight ahead and steer with the other motor. Test it first in a safe area to see how quick it turns.November 17, 2021 at 8:48 am #249815
I was using one motor to steer and it did fine
but if you take another look at the video notice
how the speed of my turn increases when I
slow down the other motor. However my main
reason to have both motors connected is I think
it would make a better video. Your point about
over revving is valid and I would like to put
more prop on them. Bring the rpm’s down and
the speed up but I don’t thing there are very
many options for these. Any suggestions?

November 17, 2021 at 5:17 pm #249830Here’s one for you, Tubs: Many of us have probably heard about the new, large outboard boats that have joystick control. The boat can spin on a dime and go 100% directly sideways. Well, sure; there are computers involved; but ultimately, it’s all about vectored thrust. The basic idea of going sideways necessitates that the engines are toed in considerably, with one in forward and one in reverse. Like you, I have two 1960 Evinrude 3’s. I put them both on my aluminum boat, as far apart as I could. Then I turned one around, for reverse, put the other one ahead and after some finagling with the angles and the throttles, I got my little boat to go directly SIDEWAYS, just like the big boats I work on. I thought it was a pretty neat trick. You should try it!
Long live American manufacturing!
