Got a new power plant yesterday. 2001 115 yami with 400 hours to replace my 23 year old merc. Got it for a good price from a guy in Maine. I just got it mounted yesterday and hope to have it operational by mon or tue. Lower unit needs some cleaning but new t stats and water pump have been installed. A lot better technology from my 1990 merc. Where do you guys mount the external oil tank? I thought it would fit in the old batter comp. in the starboard seat, but it is a little to big.
