What year/info is this motor...need help

[DamianJP]

Hey guys

I just got a engine for my nephew. Guy told us it was a 2000 6hp yamaha but I think it's a 5hp either a nissan/tohatsu or a yamaha. When I look up either a yamaha or nissan/tohatsu they seem like only 5hp and under had the internal tanks. As you will see the pic, it had a internal tank cut out at the top of the cowling and a mount above the power head.

Only info I have on engine is the stamped circle number off the powerhead since it's be repainted.

Serial ? 08568


Says use BRP7HS10 if its a nissan/tohatsu 5HP (it had a BR7HS10, what is the diffrence between BRP and BR)

And if its a yamaha says to use B7HS

Im going to need the following info when we find out what it really is...(I prolly can look it up but if you know feel free to chime in)

1)Spark plugs it should take
2)Oil Ratio
3)Lower Gear Oil

Heres the pics

Thanks guys in advanced,
DamianJP
