RC 585 Aux & SIB Outboard size?

whisper · 02 August 2012, 11:41

Hi, I'm looking for an AUX engine for my Ribcraft 585 that can also be used on and plane a Pastimo 270 SIB.

I was thinking of a Suzuki DF6 but I didn't know if it would get the SIB on the plane?

Thanks in advance

HI Alex - I think I've been down this route .......

I had (and now Trevor has it ?) a 2.6 slatted floor bombard tender which with just me and a 3.5hp 2 stroke on the back used to plane

2 up it stood no chance.

I think with a 6 you should be 'Ok' ish with 2 light adults , but I found so much depends on weight distrubution and how calm the water is.

I guess that a 585 aux would need to be around 6hp?

The sib will take an 8hp but will that be over doing it?

What is the situation here regarding the shaft length of the Aux? Will the Ribcraft use a short shaft, as the SIB won't like planing with a long?

Hummm, I had assumed that i would need a short shaft, but I'm not near the boat to measure

Your RC585 has an xl transom so a std shaft aux would need a drop down bracket.

Dangerous stuff time .....Do you really need an aux ?

But if your going to do it and the SIB is rated to 8 ..get a 10 !

DHD, does Standard mean Long (20") or Short (15")?

No not really, but I thought it would be good if it could be used as a back up.

The sib will be used for fishing and for those calm evenings when I can't be bothered to launch the 585 it will also be used as a tender when searching for new beaches

So I guess I go small and get from A to B or go large for a bit of

Investing in a pair of oars for the RC is a cheaper option

Yes and has the added advantage you can fend off (with a big clout!) other RC 585's that come too close!

And if you break down, Avocet seems to be a champion tower

Good call though Longjohn

I know someone who took the longshaft 6 off the back of the rib, put it on the Dinghy (forget the make / model) but got waaaay better performance from the dinghy with a shortshaft 4, even though they were 2HP down. The drag of the long leg totally overcame the extra gee gees.

Also remember that in small engine teritory "short" & "long" are different lengths (physically less long) to the standard lengths implied by "short" & "long" on the bigger engines.

I phrase like that so as not to cause too much confusion with the word "shorter" -
