evinrude 7.5 fuel ratio

[TRAVAS_OH]

hey there everybody this is my first post but from what i have read so far in this forum. i think this a good place to be .
i have a 53 7.5 evinrude .( found that info in this forum, thanks for the help) . im not sure of the fuel ratio and what
type of oil to use ? 30w two cycle or what . I have ran the motor with two cycle at 32:1 but im sure thats not right .
(just had some in the garage). the only thing i know about this motor is what i have read on the labels on the motor.
any info on this thing would be of great help.

Re: evinrude 7.5 fuel ratio

welcome to iboats! jmo, but id run it on modern 2cycle oil at 16:1, but some will say 24:1 is ok. do not use 30wt automotive oil, modern tcw3 oil is far superior.

Thanks for the info. 16:1 it is . My next problem is sealing up the lower unit , it leaks slowly on the floor and looks like chocolat milk after running . looks like i have a small project on my hands!

Well you have to pull the powerhead to drop the gearcase, but not a real hard job. There are some pretty good youtube videos of it. Ifou need any help with it let us know.

16:1 is the correct ratio, but use TC-W3 oil, not 30 weight car oil.

It is not necessary to pull the powerhead to access the water pump or gearcase seals.

Water pump impellers are obsolete. But Brian Wilcox makes them. You have to send him the old hub for recycling.
