*new* Merc Optimax question

[THEFERMANATOR]

The last time I had one get that bad I ended up dropping the lower unit and hooking a hose straight to the water tube, pulled the stats out and the bypass and turned the hose on full blast. Then put the bypass in and repeated this, then put the stats in and let the water run for about 10 minutes. This worked for me in the past. The thing is you need pressure and volume to flush it out. On a hose you will be lucky to get 7 pounds of pressure through the block whereas a hose can get about 20 when hooked up directly. The flushing hoses just are not big enough to flush out an engine and many manufacturers have admitted this.

i also think if he runs to bass pro, they will not cover it under warranty. sand in the system is not a defect in materials & workmanship.

Alright, I'll pass this info along. PD- I was worried myself about them not covering it..seems crappy if they don't. I've already told him If I was him I wouldn't touch it. I'd get it done under warranty if possible...I would definetly find out for sure before jumping into it. Thanks guys.

warranty isn't going to cover that, its not supposed to cover driver error

x 2...that'd be like backin' it into a dock and expecting the damage to be repaired under warranty...

Not too sure of that motor, but have you ruled out that possibly the sand chewed up the impeller to the point that it will push water at low rpm's but as soon as it's under load, there is not enough impeller surface to keep up with engine temps?

Just throwing this out there , Can it be back flush using water or air ? I am not sure just a thought ..
