The antifreeze I use for my engines/water systems is propylene glycol based not alcohol based. Alcohol can dry out rubber seals in the motor. I can’t see what you have from the pics.

If you’re going to use anti freeze just use RV anti freeze, it’s the least toxic of your options, and you should thoroughly flush your engines before launching your boat.

Secondly it’s really not necessary for the engine, just follow the manuals direction and blow the water out of the water locks after you take it out of the water. The first year I had my boat I put anti freeze into the engines but have since not done so.

If your boat has a fresh water shower you need to make sure that system has the majority of water removed.

I just finished winterizing my RV’s potable water system with RV anti freeze. When it comes time to use my RV I thoroughly flush that system and I don’t notice the slightest hint of that stuff in the potable water system.

Props to @zipper for the bit about ethanol based RV anti freeze I didn’t know that some were ethanol based, I thought they all were propylene glycol.

If you’re storing your boat outside, you should definitely fog the cylinders with fogging oil.

Captain Leon Aka @Leojay on this site has a good video for winterizing. He has owned his boat for 18(?) seasons and has had no issues.
