Repowered with 200hp

I ajusted the setting on the back of the tach still not working i guess i will take it to the shop where i picked up the motors and see if the mechanic knows whats up. I will let ya'll know what the outcome is. Yea CT_V20 i was a little scared about that much HP on the back of my 89 V-20 but i did pull the cap off and took out all the old wood in the transom and poured it with this new stuff called seacast and it is solid as a rock. Thanks for all the input on the tach.
