i have a 94 mariah talari 200z power by yamaha 5.0
never had problem with it overheating until the first trip of this season
on muffs without stat at idle does not overheat at all
replace raw water impellar, water pump, double check timing
but a soon as the get in the river temp just starts...
i have a 93 Talari 200Z powered by 5.0 yamaha I/O
