I have a 16 foot Doral tri hull bow rider with a 65 Johnson power tnt.<br />It has always been prone to porpoiseing and I am forever trimming up/down or throttling back to stop it.<br />I put a 2.5 merc on the back as a kicker and it is worse than ever (30lbs 8" off the rear of the transom), I pretty much have to leave the trim down all the time or I feel like flipper.<br />I can't really shift much weight to the bow without running cables to the front for the battery or finding a small narrow fuel tank to go under a bow seat.<br />More passengers and it seems to get worse not better.<br />Are small trim tabs the answer?<br />How small?<br />Thanks <br />Matt
