CAVATATION PLATE HEIGHT

[CHUCKYZ123]

73 30HP CHRYSLER long shaft 14'SKIFF<br />I just replaced the transom 20" from top to bottom. I see alot of people say the cavatation plate should be even with the bottom of the boat. Mine is 2" below and I have a problem with water circulation(it doesnt) at anything but full negative trim. I can run wot all day at full negative trim but only half throttle if I trim it even on hole up. <br /><br />thx in advance for any assistance<br /><br />Chucky

That motor is supposed to be at 18", unless you live in clown town and 20 works

Re: CAVATATION PLATE HEIGHT

Usually the cavitation plate is recommended at or slightly above bottom of boat. Granted some people get away with them higher. No experience w/ Chrysler.

You may be due for a new water pump or other cooling system maintenance. Fix the engine then raise it till its even with the bottom.
