boat lifts

I am getting ready to move my Supra to the lake house and store it on a lift. The house came with a 4K lift with two runners. Is there anything special I should know(besides keeping it off the chimes)? I looked at the owners manual, but it didn't say much. Thanks.

just need to make sure the prop shaft wont hit the bottom on the air tanks

can you take a look at the back of that? what are thoese two pads? any chance you can post a shot of those?

my lift does not have anything like that and puting on the cover is a bit difficult. Those platforms would be nice.

To be honest, I really didn't pay to much attention to them. I believe they are just bolt ons. Next time I go down there I will get a pic for you.

You might need to get bunk risers for that lift. I have a Bottoms Up lift and had to get 14" risers so my prop would not hit the rear of the air tank.

We always adjust the lift bunks so their similar to the boat trailer bunks.

Seems like those two pads on the back would not be of much use because they would end up underneath the swim platform.

Be careful the first time you manually pull the boat on, with the engine off. After you know exactly how far up you need to pull the boat before the prop is close to anything, then you can do it under power without much worry.

Definately raise the bunks higher. I would also knock those carpeted 2x4's off, that are acting as a guide. Repalce with some 3 inch ( or so) PVC slid down over the poles the old 2x4's connected too. Guides need to be perpendicular to the water not parallel. when perpendicular the guide will always hit your rubrail. parallel , it's a crap shoot depending on how much weight is in the boat, water condidtions, ect.

If kept it that way you run the risk of gouging/nicking you gel coat.

I'd remove those things sticking off the back.

Josh, what is a bunk riser? Do you have a link? I have a 5,000 lb shorestation that was perfect for my old Supra but my new Supra has a much bigger prop and deeper V bottom. The bunks are as high as they will go and I need another few inches.

Your bunks should be under your boats stringers. That is the safest place. They also need to be tilted inwards 5 degrees in the back and about 15 degrees on the front. I built boathouses for several years and had the best luck doing it that way.

Attached is a pic of my boat on the lift.

Mine is identical to Brad's. this is an old pic of an old boat.

Tre-- The bunk risers are the vertical pieces of steel which bunks attach to. It looks like Paul has 8 of them on his lift.
