Went out to the Shenandoah today with the old lady on a used boat I picked up this winter. I had replaced the water pump gasket and lower unit spaghetti seal in February and changed the lower unit gear oil. It ran like a champ with the muffs on at the house yesterday so I thought we were good to go. Not two minutes after taking off up river the motor putted down to a stop. I went to pull the string again and it wouldn't budge an inch. Luckily I had just got a bow mounted trolling motor so the day wasn't completely ruined. After the trip was over and we were back at the house I put the motor in neutral and was able to spin the prop. I could pull the string but it was extremely resistant. So I waited for another hour and took the cowling off and was able to turn the flywheel by hand. I checked the spark plugs and took the cylinder head off. The pistons look good but I could see marks on the cylinder from the seizure. Im guessing the motor had seized but not enough to completely ruin the engine. My question is could this be caused by a wrong fuel to oil mix ratio or is it a cooling issue? Thanks for reading and any input is appreciated
