draining the bowl?

So when i picked up my 86 nautique 2001 a couple of weeks ago I hooked up the engine to a hose and started up the engine to make sure things were working ok. This is my first inboard and i did not know that i had to drain the "filter bowl". And it became very cold the next day to where that water froze. All of the other water was drained from the system except for that "filter bowl".

Three days later i wanted to check on the engine and finish the winterization. Well the bowl and such was frozen. I was able to melt that ice with warm water and a heater. After melting i started the boat and it began to overheat.

I was just reading an owners manual and it says
"Late in the 1985 model year Correct Craft initianted a change from a water filter manufactured by Vetus to one produced by Sherwood.
THE SHERWOOD FILTER BOWL REMAINS FULL OF WATER EVEN AFTER THE REST OF THE RAW WATER SYSTEM HAS BEEN DRAINED. TO PROPERLY WINTERIZE THE BOAT, THE FILTER BOWL SHOULD BE REMOVED AND EMPTIED.
IF WATER IS NOT REMOVED, THE BOWL COULD BE SUBJECT TO FREEZE DAMAGE AND THEREFORE CAUSE OVERHEATING PROBLEMS DURING THE NEXT SEASON."

My question is what the heck is this bowl and how much will it cost me to replace because both me and my father don't know about this?

i think thats what happend that the raw water strainer cracked. My engine was overheating when i had it running again. Also the engine was not sucking in a lot of water. It would take a little but not much.

The raw water filter strains out gra$$, weeds, etc. which might get sucked through the intake and helps prevent such debris from entering the engine. You should check it periodically to make sure it is clean. Where I live, I routinely get leaves, aglgae, etc. in the filter. BKH

Eric,Raw water pump is located at 7 o'clock. the big pulley is bolted to it.One hose from the intake in the bottom of your boat,the other hose runs to the thermostat housing at the top of your engine........boat dr

Your impellar is likely now wasted. By 1 plus a spare. Find all the pieces else it will cause problems.

Within the raw water pump, lower left.

Fragmants may lodge in the t-stat housing.

There isnt one on my boat. I searched and searched my entire engine. Im now wondering if my impeller is what was causing water to not circulate through the engine. I don't want to take off my raw water pump at this point in the winter because i have anti freeze in there, but I may have to in order to figure out whats wrong with it

Eric,

Congrats on your new 2001. Love the 454 engine. Did you buy that boat in Wayland, MA? I think I saw it for sale on Ebay. I'm local to Wayland and Lake Cochituate if that's the same boat.

Good Luck!

I'd recommend getting a strainer and adding it in line with you raw water pump. It will help keep your cooling system clear of seaweed and trash that gets sucked into the water intake. here is the link: http://www.skidim.com/products.asp?dept=1006

88 Nautique- Thanks for the the picture. I see what you are saying. I plan on replacing my impeller in the spring, but I can see why it would be good for me to remove it during the winter. I plan on removing my RWP once it gets a little warmer so that I can put in my new impeller. This is all on the list of things to do for the spring.

I didn't think about that TR. I haven't seen a new impeller yet. I'm going to order one for a spare. Do the splines point straight out when they're new? If so, I guess it really wouldn't matter. Still learning.

Yes the impeller blades themselves will "flip" and correct themselves if oriented backward. What is important with that installation is that you get the hoses reinstalled on the same pump connections that they came off of. With a RH engine, the hoses are crossed near the pump, and it's very common for folks to reverse them.

That's a rare boat you have.....Not many Ski's out there with big blocks. Sure hope your engine didn't freeze and crack the block or manifolds when it got cold! If the oil starts to look milky when you start it up, shut down and look for big problems!
