Re: makeing the biggst wake my boat will make?
I have an 18ft stingray with a 3.0L and I did a lot of experienting last summer and i think i have it pretty down.
1st, 6 people is the magic number to bring (not including the rider) 2 up front (usually girls) one in each capt chair (one driving obviously) and one on each end of the bench in the back.
2nd, BALLAST! makes a huge difference. I put one 350lb on the floor in the middle up against the back bench and one 350 (usually half to 3/4 full) in the front in between the bow seats. I just use the simple pump you buy that plugs into the cig lighter and it works great.
3rd, Trim. The magic spot for the trim really makes the wake clean and crisp but too much and you'll start bouncing and ruin the ride.
A few smaller things that help but may seem over kill...... I want as much gas as possible to when i fill up i drop the trailer off the ball onto the ground because my gas cap is on the rear and it lets me get 3-4 more gallons in. Also, try and make people sit opposite each other that are of similar weight so the wake is even with a small boat you really notice when the weight isn't even.
You may be thinking wow thats a lot of weight for a 3.0L and it is, I bought a 4 blade mercury 20p prop to help the hole shot. Also, a disclaimer, I'm WAAYYYYYYY over my weight limit (1080) but I never take water over to bow or anything and i've never once though i was in jeopardy of sinking.
I really hope this helps, really its probably different for each boat but this is what i came up with after a whole summer of guess test and revise.
