Re: merc oil injection
I had a pair of 1985 175HP Mariners with oil injection, they worked fine till I replaced the engines with new mercs. They included a reservoir under the cowl and and external reservoir to feed them. The engines ran like scalded cats up until I submersed them...I have replace them with two Mercs now and have had the oil injection removed only cause I was advised to do so by more than one "experienced" sailer, not because I had any problems. Hope this helps.
