Auxilary O/B and towing questions

Hi

Okay new to the forum, so please treat kindly!!

2 questions. we would like to fit a Aux outboard but are not sure of size, shaft length or even how we could fit it without causing drag. we will be buying second hand o/b so a 2 stroke would be likely. Reason for fitting it is we want to go on longer trips but want the assurance of an aux o/b.

Second question. last boat had tow eyes through transom, this boat does not have these but seems to have 4 hook on points on the radar arch, could these be used as tow eyes? If not what are they for. (we only tow kids on a doughnut nothing too serious)

Photos show radar arch hook on points, view of stern and re-inforcing of stern. Any thoughts on the Aux O/B and tow eyes very welcome.
Thanks

be kind and let me know how you get on with installing the 2nd outboard...

I have a 2.3hp Honda 4 stroke which was used as 2nd outboard on my previous boat. I tried install it directly on the transom, but simply there was not enough space to rotate the tiller (of the 2nd outboard) between the main outboard and the tubes. It is a short shaft Honda outboard, and it reaches the water.

Since then, I have been thinking of installing a bracketm but again, I have no idea how to move the tiller as there won't be enough space even when I install a bracket...

This is something which is annoying me a lot, as the engine is ready but have no idea how to use it!!!!

on the original coastguard 4m searider ribs we used the main 40hp mariner to steer with when using the aux engine for power. Worked fine

That's what I do. Turning circle is a bit epic but much more comfortable!

not of the seariders they have long gone. CG went on to bigger and better(?) and then sorta gave up on boats whilst the govt now seems to have given up on the cg--and Ive given up on both of them! We had a 4m searider of our own with a 50 plus a 5 on the transom, fitted both on easy enough.

Ref. the Aux, If you got a 585, I'd be thinking nothing smaller than 4Hp, preferably 6. There are some oldschool 2- strokes out there are relatively slim. Also you want a long shaft.

The Aux sizes of engine as a general rule "long" is about equivalent to "short" on your main lump.

I have got a mariner 2 Hp two stroke mounted directly on the transom. This will do four knots which is enough to get me out of trouble. 110 eBay which is a short shaft.
