i have a 7.5 fleet twin i bought earlier this year. when i got it i put a new water pump in it and a new prop seal. it now pops out of forward gear i dont know if it did it before i did not run it prior to work. i do know that nuetral is not in the middle. you have to put it more in the forward range the gears look good in the lower unit. is there an adjustment for this. please help i need it for duck season thank you Tim Gaskin
