Hello, My wife just aquired her 3rd new (used) boat last weekend, a 2003 Ciera 2455 w/5.7 carb and Bravo-III dual prop. It's quite a step up from her previous 1998 2052 Capri Cuddy 4.3L Alpha drive.
Now being the "chief" mechanic, I'm a bit overwhelmed with all the water pumps/water heaters, buty doing may best to catch on fast....but looking for much needed tips/quirks on these models/drives.
This weekend we took it out for the maiden voyage in Lake Washington, (yes the weather was crummy! +46F) first thing I noticed, no tach reading? could have/would have sworn I had a signal when they fired up the boat in the shop in Portland? not sure where to begin the trouble shooting? what's the best way to get to the back of the gauges on these models? pull th epannel from cockpit side or can I get to the tacj from the access panel in the head?
Second question is the water temp? our 5.7 is closed system, seems to have a small heat exchanger transverse mounted front of engine, bigger hoses, radiator size?then there are two smaller diameter hoses, (heater hose size) that run over to the hot water heater box. Our first run, idling from the launch, the temp pased 175 (on the dash guage) I was turning around and heading for the dock when it settled down and hovered smidge over 175, but not quite the next tick mark (Fiara guages) assuming thats 200 as there is one more tick then 250max.
Since the temp seamed stable, we continuded on, did a couple of WOT runs, backed off, repeat... idled down, putted, tried out the trim w/trim tabs...(again new to us) noticed if I pushed it... the temp would climb to 200'ish...if I idled down it dropped to 175+,
The temp seems high to me? would the impellar fluctuate the temp on a closed loop system? does it sound like a sticky thermostat?
I don't have a maintence history, so best bet is change them both? could I be missing some other factor?
Looking forward to the insights,
thanks,
