Take old one to parts store. Compare the two. If they are the same and they should be, then but the cheaper balancer.
I would remove it and inspect it though. They should not wobble when the engine is running.
Never seen a "marine" version of the balancer. Only issue you might have is that they sometimes drill the balancer to balance the engine. May want to see if has balance holes drilled on the backside and compare with the new one to see if they are close to the same.
