just wanted to let you know that my loss of the 2 cyl. was not from water . I thought if it was water than get rid of the water. so i fired up the engine just long enough to pull a sparkplug wire and it did not change anything so i went back to basics, and rechecked everything and found the wires for cyl. 3 and 4 were crossed from before i had even got the boat . so the thing i recommend is for you to please not jump to fast conclusions with peoples problems . because i was afraid all my work restoring the boat was a waist. because now the engine runs great. thanks anyway .chris
