Getting your SIB planing

Thought this might make for an interesting thread and it's a question that lots of us need to know when searching for the lightest rig to suit our needs. So what sib have you got, what engine and how many people/ stuff can you get on the plane? Me, bombard aerotec 420, 15hp mariner 2 stroke, 3 adults and a child on the plane without too much fuss. 4 adults managed to bounce it onto the plane with a struggle.

I have a Quicksilver 380HD, ali floor, with a Mariner 10hp, it will plane easily with 2 adults and basic gear, but have not had time to experiment with more yet.

I have a Quicksilver 380 hd with mercury 15hp 2 stroke, it planes with 3 adults well but 4 is a struggle. I am considering a 25hp 2 stroke Yamaha, how do you think that would perform?

I've got the same outboard as you Mike

previously had a Yamaha 25hp, the yam had lots of low/mid/top end grunt on a sib and was an excellent engine, BUT.... It weighed around 52kg as opposed to 34kg on the Mercury

18kg extra is a huge difference off the water

Honwave 380 air floor, Parsun 9.8 4 stroke.
Easy plane 1 up with gear, a little longer with 2 adults but gets up ok. Would love a 15/20 hp but the Parsun works well for my needs.

I have a Zodiac Cadet 285s (2.8m) with a Tohatsu 9.8.
With this engine the Zodiac goes like a rocket, planing pretty much instantly with two of us on board and achieving close to 20mph.

Prior to the Tohatsu l had a Mariner 6hp and the boat would plane two up with a few seconds taken to get going. It would get up to about 14mph.

The Zodiac 285s is a great little boat, it has a solid floor and air keel so planes and handles really well.

Regardless of type and Power you can easily Kill even a Decent SIB's potential performance by Bad Loading and or overloading of gear.....not to mention Passengers.
IMO It always pays to consider the type of jaunt you're on,the expected weather AND type of Crew...the smaller the Boat the more you need to plan.
Especially important if it cuts up rough!
I used to carry a lot less gear in good weather with the Wife and a couple of Kids on Board my Zodiac..
If alone on extended trips you can often afford to take more "Stuff"...
