Flushing Bravo I
Just purchased 1999 Powerquest 260 Lengend with 454 Mag EFI / Bravo I drive. Only 68 hours on boat. Summerized by dealer 2 weeks ago. Here's the question? Started it on the trailer with the Mercruiser low water nose cone attachment. Heavy duty hose 1/2 open with good water flow at start up. Ran the engine 3-4 minutes at no more than 1000 rpms and didn't notice any difference in pressure. Temperature gave up to about 120 degrees. Didn't see much water out the exhaust but after 3 minutes did notice a little water and condensation out my tips and underside of the drive.. sound normal? Also, slight smell of anti-freeze, but just thought it was residual for winterization. Any thoughts would be greatly appreciated.

Didn't see any difference in what pressure???????
Most boats wil not get up to full temp on a hose unless they are run for a very long time. After about 20 mins my temp will bounce back and forth between 100-140* when the tsat opens and closes.
You should have quite a bit of water coming out your exhaust. Do you have swichable exhaust???? Is water coming out the drive exhaust/prop???

A 1999 454 should get up to about 165*. It has a 160* thermostat I believe. It's not going to happen in only 3 mins though. My motor will reach normal temp when I run it on the hose.
Like Lenny said, you should see plenty of water coming out the tips.
