Aux for Ribeye 785s

Hi,

Having recently acquired a 785, I'm looking at options for an Aux engine (as one of the main reason for the boat upgrade was to go a bit more offshore / longer distance).

I'm hoping I can get a small 2 stroke (or even electric) which I can keep in the underseat locker and bring out in the case of a main engine issue.

Realistically what's the best / smallest HP / KW that might keep a 785 moving and bob us back to shore?

forget electric-useless for this, 8hp 2 stroke minimum and make sure it will bolt onto transom before committing to anything if possible. no point it being in the locker IMO as if it is rough you won't be putting it on the transom easily.

20 miles is about 4-5 hours on a boat that size i would wager based on my 6.8 with an 8hp 2 stroke aux.

Thanks Xk59D, it would have it's own bracket, just don't want it on all the time as they just get bounced around - but I see your point that you don't want to be trying to put it on when the s*ht hits the fan.

the lightest 2 stoke you could buy is one i have i think, it is 25kg for yamaha 8hp 2 stroke, i did have a 54kg 9.9 suzuki briefly but there is noooo way you are putting that on whilst on the boat and moving around, if the stuff hits the fan the 25kg will be a real struggle too.

on a bracket isn't ideal but if the choice is a bracket or a locker then needs must, amazing on a 7.8m boat an aux won't go onto the transom though

With wind or tide or both running, 8hp wouldn't do fart on an 8m boat. OK in calm conditions, but useless if it kicked up.

8hp will be no more than adequate on an 7.8m boat.....hence I said minimum!!!!!

If it kicked up then 20hp may do nowt! It is all relative and worst case can keep you away or close to land as situation dictates until others arrive if need be.

Never seen an 8hp single? 6 is biggest single I know of?

I don't understand people not advocating an aux, seems to be a Solent thing. Up here you rarely see someone without one or in company.

Personally I never go out alone without my aux, never used it in anger but gets used every time I'm out and started before I leave the dock.

Don't know why I put 8 single, probability getting mixed up with 5hp.

I always keep the aux on permanently, but my main engine does not have a limp home as my Honda did. Plus I normally would use boat without company a nd not in the Solent. But if I cruised in company, had a means to share fuel with a neighbour's boat (if required) then I'd probably view a tow as an ok alternative for a short haul.
