i have a very large TLC. it has two ballast tanks, forward and aft. need them to avoid carrying even more weight around, also i can empty them to float of after beaching. now heres the thing. the pumps keep quitting on me. i have tried graupner,robbe pumps no good, i have tried windscreen pumps, no good. just put in a new one. lasted for about one fill then packed up. the motor housing was very hot. taken the old one apart and can find no reason why its quit.
can any one recomend a pump that is more reliable? i also will want one for my sub but there is no way i am putting in a windscreen pump(used by several other models) till i am happy they are reliable.
any ideas
