Auxiliary outboard

Hi Folks
What is the smallest aux outboard for an Avon Searider 5.4 as there seems to be very little room to fit anything, main engine 90hp 2stroke Mercury?
Nick

Probably something like a 5hp yam 2 stroke its about the smallest thing that will push the boat. Next thing smaller is the little lightweights like the yam 2b or merc 2.2/2.5 or 3.5 but all a little small to be particularly usefull

What Beam said.

Rule of thumb is roughly 1hp per meter. Tohatsu 5hp 2-stroke would be a good call too. You basically want something with a narrow engine cowl. When main engine is on hard lock there"s no contact with auxilliary. Look at long shaft too.

Also consider some sort of anchor point to ratchet the auxilliary in the tilted position, as the tilt locks on these smaller outboards wont stand up to the vibration when underway.

consider a high thrust engine [yamaha] better at displacement speed, if you can mount it but not slew for steering set it up fixed and steer with the main engine not as responsive but will get you home ok it worked for me on my ribquest.

Although a 5 HP motor will take you back to terra firme won't work well on extreme currents, harsh winds, personally wouldn't dare go any less than a long shaft 9.8 HP motor with a high trust prop. If can find a 2 strokes motor much better...

Happy Boating
