My adventure had a 100hp 4 stroke mariner on the back. It was pretty stern heavy, wouldn't want any heavier than that. I was always toying with a bag of sand up front as in chop it was better with someone sitting up front. I don't know what it weighed, Google will tell you... It was a 2006 model.
Really happy with my sr5.4 90yam
I get about 35kts 4 up, she is fairly thirsty at about a litre a mile but weigh this against servicing costs etc its a good compromise
The hull is still flooding and she's straight on the plane, if I was to put a four-stroke on I'd look at a 70,
