I just purchased a previously owned '93 Sea Ray Overnighter Mercruiser v8. Unfortunately without a manual and can't find one anywhere. Any chance you could readers digest what it says about gasolines containing alcohol?
Serious rookie here. I bought my first I/O and I'm concerned with the fuel to be used. Its a '93 Overnighter with a Mercruiser V8. The previous owner said he just used 87 octane out of the corner gas station. But I've been reading I should be using an additive....and reading no additive is...
