Correct Oil for Mariner 5hp 2003?
I bought a second hand Mariner 5hp 2 stroke, manufactured in 2003 (Belgium).
It has a sticker on it (nor original) saying 100:1 oil mix, but looking through the User Manuals from the Brunswick site, I can't quite work our which is the correct one for the 2003 manual.
The 90-10102R30 manual shows:
"After the break-in fuel mixture is used up, use a 100:1 (1%) gasoline/oil mixture
in engines used for pleasure applications. To provide additional protection for
commercially used products, a 50:1 (2%) gasoline/oil mixture is recommended"
But the 10102050 manual reads:
"After the break-in fuel mixture is used up, use a 50:1 (2%) gasoline/oil mixture. Refer to the table (following) for mixing ratios."
I read somewhere that using a 100:1 mix instead of 50:1 makes the engine run hotter.
I also notice that the previous owner has a BPR6HS, rather than the specified BPR7HS-10 as specified in the manual.
Wondering whether those two things could be connected?
Any help would be appreciated.
