Marlon boat trailer leaf spring capacity

[Kasbien]

Hi everyone,

I've got a 14' Marlon aluminum boat and 20hp Tohatsu outboard. Fully loaded, the boat weighs around 400lbs. Marlon uses a one-size-fits all approach with 1250lb capacity leaf springs for their trailer (which extends or collapses to suit each size of boat they make). The ride is very jarring/hoppy in my opinion... even rolling 10km/hr down a gravel path is road has been enough to back off my transom straps and unseat the boat.

I'm thinking I would benefit from swapping leaf springs to a lighter weight capacity like 800lbs. That sound right?

What PSI in your tires?

What PSI in your tires?

I think I went based off the sidewall. 65PSI

I would try reducing that down to 40-45 psi. You don't need the tires at max pressure for your light boat.

I've got a 14' Marlon with 20hp Merc. The Road Runner trailer is definitely a harsh ride however I've dropped PSI in the tires to 40 and the ride is considerably improved and I've seen no adverse impacts to the tires as a result over two seasons (I fish year round)

Thanks guys. I'll give that a go. 65PSI seemed awfully high but Marlon concurred with the sidewall.
