So much for Merlin engines in spitfires and failing bridges where did all that come from?...Many thanks for the back on topic comment about outboard
swamping in the San Juan Islands
As stated previously we usually use a 2 horse power British Seagull Minus on the walker bay 8 which is perhaps immersed a bit deeper than the design specification due to crew weight...but with anchor
, chain and Rode
in the bow for safety
trim: we seem to get away with it. Also it is possible to adjust the distance between the propeller
shaft and the clamping bracket on that one: though I have not bothered to do it yet.
During July we tried to transit through the Canal
between the Pender Islands with the 2 hp heading west and had to bare off before passing under the bridge. We tried again and succeeded later in the day, So this is what prompted the curiosity thought to acquire the 4.5 horsepower British Seagull to try it out on the walker bay 8, I did not think the the additional 12 pounds difference between the two would be such a huge issue. (The adjustment of motor
height on the Century model of 1963 vintage is not possible)
I conducted the test in the calm sheltered waters of the Deas Slough of the Fraser river. We had more push against wind
, but no appreciable increase in speed. However the motor
did not seem to be able to reach top revolutions possibly due the the immersion preventing the exhaust
from escaping efficiently, thus causing an excessive back pressure. Back in the close proximity to the boat
Three power boats nearby heading in different directions churned up the water
causing a partial swamping of the dinghy
and the outboard
motor died. Causing it to subsequently refuse to start. One of the ski boats seeing us using the oars towed us to the dock
. The next day back at the workshop it started on test without any difficulty.
Thus I find the report of the problem in the San Juans islands interesting and possibly similar to my testing the 4.5 HP experiment
... In various parts
of the world there are River Bore's and high water
flows through narrow channels between islands that are affected by tides that have to be challenged at slack water. So has anyone considered the merit of having both an inboard and and outboard running at the same time in these situations? or has the outboard proven too vulnerable to be useful in the very turbulent water.?
