I am begining the revamp of my 26' Starcraft Islander. 170 Merc Aluminum. I have two questions:<br />1. Has anyone used vinyl Deck material to replace the plywood decking, and their success?<br />2. I've heard little good about 170 aluminum merc's is there a v-6 that has a similar bolt pattern and would be a good replacement?Any other suggestions?<br /><br />Thanks!
