Nice to see the picture's of your new Searider!
From the Dutch Avon Searider Club some ""official" Avon Searider Manual Instructions.
Consult Your Manual for detailed instructions on egine mounting and peration.
The type of engines suitable for a 5.4 searider are longshaft as opposed to shortcraft. With the engine in position, the cavitation plate should be near level with the keel at the transom.
Single engines will need to be offset on the transome 25 mm( 1 inch) to starboard from the centre of the boat. This is to counter the centrifugal effect the engine has on the boat which can cause handling difficulties.
All holes drilled through the transom must be sealed to prevent water penetrating into the grain of the plywood.
Our Club experiance is as the adviced in the manual instuctions.
Average transom Hight SR5.4:is 52,5 CM
Yes to seal the plywood under the alu- strip is very important!
(In our opinion this habit is the only weak point on a Searider has !)
If it had't had this it wouldt last for ever.... (poor Avon sales mangers, nobody wouldt need a new one!!)
Also take precautions if you mount pieces (console etc.) to your floor.
