86 v20 CC 2004 Optimax225 vs. 2015 Merc 4 stroke 150

[bill2089]

Hello, just picked up a 1986 V20 Steplift Cuddy. I need and engine, the choices are:

1. A 2004 Optimax 225 HP with about 600 hours
2. A 2015 Mercury EFI 4 stroke 150 HP with 2200 hours.

Both run great and are comparable in price. Thoughts? I have always been a sailor, new to the outboard life.

Thanks for your input!
