That's what I do but a different way. I trailer just a few hundred yards to the ramp from my house. I do a warm up on the trailer at home so I can just drop and go. Very busy ramp with no dock.

Same here. Always nice to drop and roll and with no surprises. I've seen a lot of some pretty messed up chit go on at ramps. Shovel fights, golf clubs, you name it. Years ago I'd get into it now I just crack another beer.

That's exactly why my boat sits on a lift. Push a button and in the water the boat goes. No boat launch drama.

Before I leave the house, the batteries get a quick check/ charge. The engine gets started and warmed up, drive gets greased (old boat had grease fittings all over the drive) trailer tires get aired up if need be.
Overall visual check and a couple times a season the timing light comes out for a quick check (how I found out my old MSD distributor was corroded beyond belief )

I like to dunk and go!

It is quite a bit of fun to watch a public boat launch on a busy day. (Especially jet ski owners)

Plus I know when your on the water. It's what got me back into boating. Good, bad, indifferent. Back in the game. Lol

A lot of myths with aluminum heads... we did a swap in the past but tested by MPH and ET... engine was in car. Everything being fairly equal we actually ran the same MPH but a bit better ET... long story short the engine did take another 2 degrees of timing until MPH flattened out. Result was 2mph and .15. Was on a 10.50's car. So this shows the weight savings was worth more than the power. We feel overall it's making about same amount of power but took another 2 degrees timing to get there.

biggest advantage to aluminum is weight and ability to repair them.
