Just received a 1977 Silverline with a 1977 Evinrude 140hp outboard which has been sitting up for 7 years....Boat seems to be in good shape...my question is after I drain the gas and all from the engine what is the fuel/gas mixture....50/1??? Please advise thanks....:confused:
 
yes 50:1.

Good idea to also check/change the gearcase oil.

New water pump impeller would be wise too
 
Curiosity question

I have a 1990 s-10 pickup..4cly with 94-104 horses...I have a 1977 Silverline 16footer/140hp evinrude 1147lbs...towing is no problem as I brought it home from 45 miles away...but if I put the boat in the water do I have enough weight to retrieve it???:confused:
 
u should,unless on a very slippery ramp..not familiar w/silverline,but the length and weight does'nt sound tough for ur trk.
