The 13 pitch prop is the main issue.... Get a 9 or 10 for 4 people....

I have a 4.1m rib with 30hp 4 stroke. All set up perfectly, but I have to move people around the boat a lot to get it to plane with a 13 pitch prop. I now have 12 pitch prop, and with care it will plane with 4 people on board.... Not all props are equal also....

Borrow a 10 inch pitch prop would be my advice, then buy the best.

Use the 13 when out with a light load, if you miss the top speeds....

Thanks Simsy. I'm thinking the 11" pitch plus the 4 blade over 3 blade should definitely do the job. Will keep you posted!

And get the weight forward until she's up on the plane !
I did a PB2 course in a 4m SR4 with a 25 mariner fourstroke on it once with two seriously obese people , I'm driving and they are sitting one either side on the tubes, the throttle was wide open and the engine was bogging away and the bow is in the sky, trimmed in all the way 12'' pitch prop.
Me '' err can you both move forward a bit, err a bit further, mmm, further,''
And when they were both ,practically sitting on the bow she popped up on to the plane, at which point they had to move back before the prop came out of the water !!

I had a zodiac furura with a 30hp, i fitted a set of doel fins to cavitation plate (abouut 25) would plane with 2 adults towing a ringo with 2 teenagers no problem. without the fins no chance so they are well worth investing in for very little cost.
