Engine size for Zodiac Mark 2

Hi, I am in a quandary about the right engine for me and so I will throw the question out there for the forum to offer advice on.

Firstly we are new to sibs and I am getting in to this by accident. I recovered a vintage mark 2 from a skip and i have done the repairs and it is now holding air nicely.

We are a family of four and intend on using the boat to pootle from cove to cove and along the Mediterranean coast or France and spain. It might be nice to tow the kids on a ring later on but just getting out on the water would be great.

Time to source an engine. We are on a budget. We live in France and I am obliged to take a training course (costing around 400) similar to the RYA Powerboat 2 course if I run any engine above 6hp (although this might be a good investment for our safety) It makes me wonder if a 6hp would be any good on this sib and while I understand we could forget towing the kids, it would be a lower cost option. Would it push alone the sib at a reasonable pace? I can always change for a more powerful engine later on if I feel the need.

Alternatively I buy a second hand 9.9 or 15 and future proof the purchase.

Thanks for any help

Specs Say 8hp min rec - 20- 25 rec. Id say 6 is too low, 15 + if you are talking 4 up -2 + 2. any training is worth much more than the required piece of paper.

6hp will give you displacement speeds only.

15hp min to give even a half reasonable plane performance with what I'm guessing is 2 adults and 2 children.

What's the SIB length & transom HP rating? Is it an alloy or wood floor?

I regularly drive a small aluminium boat with an old yam 2 S 9.9hp that has been converted to 15hp and it's pretty good, with Two/ three adults in. It's a lovely outboard and starts first pull and had excellent power to weight ratio. If you can find one that that type of old Yam would be a good first engine. David

Thanks guys. The boat is 4m20 and wooden floored with an inflatable keel. Transom is rated to 55hp!

I just found out that in Spain I can use up to 13hp with no licensing requirement and we usually camp there as it is cheaper and more to our taste so I think a 9.9 (maybe upped to 15 - cheekily) would suit better. The Med can have some proper chop on it (especially in the afternoons when the wind gets up most days) although tides are less of a worry I believe. Getting home against a wind in the afternoon might be a slog with a 6.

Thanks for your help

Ahh OK I wasn't sure if the older Mk.2 models were 4.2m as well. That's quite a large heavy SIB so I'd update my thinking to 20hp+ for a decent performance 4 up on the plane.

Yamaha use to do a 2 stroke 13 hp just for the reason you are explaining and all it needs is to adjust a screw to up grade it to a 15 hp I know this because I was bidding on one a couple of years back from a dealer

Its a short shaft.

Ive had a Mk2 and would say that if you want to plane you will need 15hp minimum. A short shaft 25hp 2 stroke would be perfect.
