5.4m Avon Searider Auxiliary...

badbaws · 16 July 2011, 23:56

I know there has been threads on Auxiliary Engines before.. but I thought would add a specific for anyone with a 5.4m.
I am running a longshaft 3.3hp Mariner (year 2001) and it pushed the searider along at max 4.8knots, and at about 3/4 throttle at 4.0 knots, with two adults and approx 60 litres of fuel onboard.

Being longshaft now requirement for any extra outboard bracketa, just clamps straight onto the transom and can be turned onboard and clamp that way round when not required.

What A-frame have you got? I've got a 3.3 in the garage.

The boat never came with an aframe as is the deluxe model.. and I am keeping it original, so not fitting one, which leaves plenty of space..

Also being the deluxe model.. I lay down under the bow and at 6ft 1 there is enough room to lie underneath the covered bow and therefore may try a night overnighting on the boat somewhere... get a bit of foam and will be all sorted..

5.4m with a cuddy cabin.. can't be bad!

I have a spare tohatsu 3.5(short) but cant figured out best way to put it on the transom on the sr 5.4. Not much space as having the heavy duty navy spec A frame. Any ideas what is the optimal way with this set-up? Not sure if it need to live on the transom all the time, maybe only put it on place in case of emergency.

With the Navy A-frame, there's practically no room at all. It's in just the right place to obstruct everything.

OK, then its not only me... Have also considered removing the A frame, but try to figure out something, the forces created by a 3.5 is not that great( keeping it on the transom in high speeds creates maybe higher forces than to dribe the boat with it). Reverting

Trouble with a shory shaft as on the standard transom is too short.

I've not had that problem using my little DT2.2 as an aux-but I'm using it trimmed quite a way out to get get the prop away from the transom. It just isn't powerful enough for anything other than flat calm
