Howzit, now you are in the game mate, I have a tip top revamped Ski Vee 14' 6" (Proper) with 2 x 30 Yama (3 cyl - Elect Start) - I use to have 2 x 25 Yama (2 cyl) on the Ski Vee, pull start though. Considering, or I assume you will be fishing Moz waters? Well - then you MUST have 2 outboards (not according the law / SAMSA Bull Dust ect - different country, different laws anyway for starters) - Just meaning - you don't have proper rescue services in Moz, should things go tits up....
So you wanting to put a 1 x 50 on....hmmffff, yes it's an idea, but what do you do when the motor bugs out? (In Moz) I use to operate Inhaca way back with the 2 x 25s...but upgraded to Elect starts.... still have the 2 x 25s...old, but was in tip top back then.
Of course it is a wet ride (LOL....use swiming goggles) - The plus point about these small craft will be, should a wave break over you, the water just runs off, cause of the lowish gunwhales (ensure all electronics are well secured and insulated) - Can give you lots of tips, In the Congo at the moment, so perhaps you should come check my set up out some time, and you will get an idea. Another tip is to re-enforce your hull - if you gonna surf launch. I do not have those extra side buoyancy aids / pontoons, but have seen them. My Ski Vee is rated for 4 PAX, however I have never fished more than two. I will be getting back into fishing later in the year, due to being too busy at my place. Keep in touch
