noticed that my starbored engine 350mpi bravo 1 drive was heating upto 175degrees alot faster than my port engine. however after cruising for about 10-15min the port engine eventually catches upto the other?? i thought maybe i had sucked up some debris in that drive but flushed both units several times and it still seems to heat up alot fater than the other. not sure what to do next, disconnect engine hoses and check for additional debris?? i did churn up some sand a few weekends ago but had a 40min ride home afterwards i would have thought it would have cleaned most of it out?? not sure any thoughts??

interesting, so for the motor to warm up to 175 degrees in about 5 min is no problem? and is 175 too warm?
additionally, when i flushed both systems they both seemed identical in terms of water flow.

i apologize but can you elaborate... i assume you're speaking of the hose that connects from the water pump to the transom assembly??
sounds like this is a common problem with the bravo drives??

motor dont have to come out to ck it. 2 bolts hold the adapter on that the hose connects too at transom .you will need 7/16 wrench.. under that adapter you should be able to stick your finger in the hose thats there ..corrosion builds up around the outside of the hose and shrinks it down to nothing ..ive seen more guys remove thermostats replace impellers and circ pumps only to find its the supply hose that wont pass water
