Default Checklist to bring engine alive (after +3 yrs winterized)

Hi guys.

I'll be waking up a +3yrs winterized boat in the very next weeks.
Your check-list will be important to decide the business.

Regarding to engine (merc 260hp MPI bravo 3), maintenance will be done before waking up and following items will be replaced:
- oil replace (engine and leg)
- filters (oil and gas)
- spark plugs
- belt
- impeller
- exhaust gaskets (I want to open exhaust system to visually inspect manifolds and risers)
- I will be present when they remove spark plugs and oils (to check water presence).

Now, I would like to hear opinions from you.
Besides this, what else should I check/pay attention on engine/leg when running it after all this time?
And what about comfort systems? She is equiped with black water tank, macerator, heated water, stove+mw+sink... what should I double-check?
Electronics (VHF, GPS, sounder), etc?
(no AC)

Any idea will be welcome!

Thank you.

That's a good list for the engine but I would start by verifying the engine turns over and is not locked before investing $s. I would also be concerned that 3 year old gas may be bad and slug in the gas tank.

Regarding the rest of the systems as long as they treated well for storage they should be fine however things with rubber and pump may be bad, rubber stiffens and pump can lock or leak.

-> mystery oil into the cylinders 24-48 hours before turning over the engine.

-> Impellor change before turning over the engine

-> batteries charged before turning over the engine.

-> I'd consider polishing the fuel or pulling from an portable auxiliary tank temporarily.

One way is just to install a battery and see if it cranks over and another is to use a socket and breaker bar on the crank center bolt but turn it counterclockwise wise to prevent breaking the bolt if locked. Another method is to use a strap wrench on the balancer to see if it turns.

PS call me Mike
