|Original outboard and bracket. First launch in 2006.|
The boat is small and light enough that a 4hp will do under calm conditions, but this being Newfoundland, calm is uncommon. A rule of thumb is 1 hp for every 500 pounds of displacement, so another 6 would have been fine. The deal I found, however, was on a new, but old inventory, Johnson 9.9 hp, long shaft, 4 stroke.
This new outboard weighed almost double the old one, and the original adjustable bracket struggled. The springs did little to help with lifting, and it had a lot of play which sent vibrations through the hull. Another upgrade was required.
In 2008, a new bracket was installed. This model has much heavier springs, making raising and lowering the motor almost effortless. It also has more substantial arms, so vibration transmission is lessened. I just should have bought one with longer arms. If not careful with positioning, the prop liked to take chunks out of the rudder.

|That 3M 5200 was difficult to unstick!|
|A test fit.|
Generous amounts of sealant were applied to the new 2" straps, and allowed to mostly set up prior to installation. I hoped it would help a little with vibration isolation.

Accessing the nuts requires crawling into a cockpit locker and laying on the hull. It is a tight squeeze, and an unpleasant task for someone as claustrophobic as me.

Then everything was bolted together with some fresh 3M 5200, and I was ready for another season.
Serenity now had a much more suitable engine bracket, better reinforcement for the mount, and the propeller was pushed just enough away from the rudder that I was no longer chipping little pieces out of it.
