  1. so got every thing up and running plates in and cooling system holding anti freeze.....ran the boat for about 45 min today and it never got above 135.....seems to be working great
  2. the heat exchanger is a mercuries brand i will look and see if it has a model number the boat also picks up the water from the bottom of the hull instead of picking it up from the out drive ......in the mean time do you know if the windshield on the1994 1830ss sport is the same glass that was on the 1992 2000 sl sport
  3. so there are two different fresh water cooling systems it appears .....one as you stated the fresh water never enters the exhaust manifolds it only runs trough the block and the heads and for that system you do not use the plates that block off the manifold and riser so the raw water flows trough both and out the risers..... the second system the fresh water flows trough the block and heads and also trough the exhaust manifold and then back into the cooler for this system the manifold and the risers are not connected to each other the plate that i am talking about keeps the water in the exhaus
  4. If it does not enter the exhaust manifold then why the restrictor plate between the manifold and riser
  5. tried to do a pressure test but with the ports open directly into the risers it would build no pressure at all so I will get the new gaskets to separate the exhaust manifold from the riser and then try a pressure test again ..... I believe that the previous owner when rebuilding the motor put the exhaust system from the motor without the fresh water system on the mother that had the fresh water system and did not know about having to have the restrictor plates in them ..... explains alot
  6. Thought so I just wanted to make sure all cooling systems worked that way before I block it off
  7. I have a question for the mechanics out there I recently bought a 1994 1830 sport with a 4.3 MerCruiser with a fresh water cooling system on it. And I am finding more every day that the person I bought it from was not completely up front about a few things or just did not know what he was doing he .....told me that he bought the boat and found that the block was cracked and that he got a new block and by new block I believe he means new to this boat ..... he and a friend that is supposed to know about boat motors rebuilt it .... he said they put it in the water and ran it for a short period
