1976 Mercury Thunderbolt 1150 / 115 HP In-line 6 clyinder

[Trauma King]

I have a 1976 Mercury 115 H.P Thunderbolt in-line 6 cylinder does this have an oil resevior like an auto, oil injected from a seperate entity or is it mixed with the gas in the 36 gallon tank in the boat. I do not have experience with the older moters from the 70's as I have only had New Yamahas from the 90's and they were fuel injected. I am doing a total restoration of the Boat ( 1972 Thunderbird Apache 187 ) and this is the motor it came with. If i have to I will have the entire motor re-furbished for authenticity. By the way s the power head in the 115/1150 the same as the 135 HP? and if so what is the minor alterations to convert it to a 135 without and exterior cosmetic changes.


Thanks for the time and responses I readily awailt you help.

That engine has to have the fuel mixed at 50 to 1 mix and if your not going to do a complete overhaul the changes are alot more than minor to convert it.
