Picked up a Larson 1800 Shark special edition today.
Does anyone have a step by step instructions on oil change? where is the drain plug? Also what are the best spurk plugs for this boat?
Are any of the oil additives safe or recommended before the oil change to flush all thd junk out?
This is my first boat!!!! So any pointers will be appreciated.

I can offer some generic comments - I don't know that engine. The drain plug will be located low down on the oil pan - if it's in a bad position you can get syphon kits that will suck the oil out of the level-check tube.
Don't bother with additives. After changing the oil, run the engine for a while. If the oil gets dirty real quick, then change it again.
If you're going to be doing your own maintenance, you really need to get a Mercruiser engine manual.
