Just picked up a Mid 90's 40hp Tohatsu 2-stroke. Engine is super clean but I noticed a small leak (Black, somewhat sticky) on the water pickup in the lower unit. From what I've read, It could be a lube leak or old Gas/Oil. Checked the lower unit lube and it's black and shows no signs of creamy consistency or water. Due to the fact that it's an older engine I'm thinking the smartest route would be to get the LU pressure tested because there might be bad seals. Anyone know of a good place to go that won't try to rip you off and does good work?
