    "Cutlass" Bearings: Johnson Duramax vs Morse Rubber ?

    I will be replacing both sleeve bearings on my boat. In my search for replacements, I came across these two brands, both of which are manufactured in the USA. There is a significant difference in price between the two. I'm looking for first hand knowledge as to the quality of the Morse Rubber...

    Riser Extension Blocks - Full Closed Cooling ???

    As long as you can get sufficient coolant flow through the 3" riser, it should work. I have the dry joint exhaust and have it configured similarly to your first diagram. In the Dry Joint Manual refer to the closed cooled warm riser diagram in the back. The riser is positioned with the outlet...

    Lifting the Engine 5.7L - Weight

    I had the same concerns using my engine hoist to lift the engine and transmission, mounted on a cart into the back of my truck. I opted to just install the manifolds without the spacers and elbows. Just block off the openings in the manifold so nothing can drop in during transport and...

    Mercruiser Warm Riser vs Cold Riser Configuration?

    2003 Mercruiser 6.2L MPI Horizon MIE. I will be replacing the manifolds, 3" risers, and elbows over the winter. The engine is currently in the cold riser configuration. The obvious benefit of going with the warm riser is the risers should last much longer with coolant running through them vs...

The older 2003 engine has the Cool Fuel 2 and the check valve between the transmission cooler and high pressure fuel pump module cooler The newer 2007 engine has the Cool Fuel 3. and does not have a check valve. Just curious to know what the...

    What is the Purpose of Check valve Between Trans Cooler and Cool Fuel 2 Module?

The newer 2007 engine has the Cool Fuel 3. and does not have a check valve. Just curious to know what the purpose of the check valve is...

    6.2L MPI Horizon MIE: New Long Block. Runs rough above 2000 RPM Under Load

    I had a 383 long block built over the winter by a reputable shop. The engine ran on the dyno for about an hour with a carburetor and ran great. The MPI intake manifold and TB was then installed, and my distributor set to #1 with #1 cylinder tdc. by the engine builder. I completed the assembly...

    6.2L Mercruiser MIE: Close Cooled Dry Joint Exhaust. Convert From Cold to Warm Riser?

    I will be replacing the exhaust manifolds, risers and elbows. The old parts were also dry joint style. When I removed the parts I noticed that the system was installed as a cold riser setup. From what I have read, the warm riser setup will help minimize moisture forming in the exhaust so I see...

    6.2L Mercruiser MIE: Drive Plate Mounting

    The parts diagram shows lock washers under the mounting bolts but the bolts I removed had no lock washers, just the reddish thread locker patch on the bolts. Should I just use Loctite 242 or Loctite 242 and lock washers?

    MX 6.2L MPI Horizon MIE: Rebuild Recommendations Needed

    This thread is a continuation of my previous thread where I had the oil analyzed and it had antifreeze and high metal levels in the oil. I want to have a boat I can depend on next season so I think the best course of action for me is to either purchase a new GM long block or have one built...

    6.2L MPI Horizon MIE Oil Analysis Shows Antifreeze

    Changed the oil in preparation for winter storage and sent oil samples out for analysis. The report for one engine came back with with high levels of the elements found in antifreeze along with wear metals elevated. Roughly 50 hours on the oil and 650 on the engine. Engine seems to be running...

    Looking For Charles C-Charger Manual. 3 Bank Charger With 5 LED Charge Indicators

    Unfortunately the label with the model information was ripped off. It is original to the boat, which is a 2003. I looked for a picture of this charger in hopes of finding the model number but did not see one like this. Batteries 1 and 2 both have the red LED lit and the green LED lit. I can...

    Rust Treatments

    In the spring, I need to get after some rust spots on the engines and transmissions. I read a thread where Scott Danforth no longer recommends the POR15 because the formula changed and it no longer works well. He did recommend the Rustoleum Rust Reformer which is relatively inexpensive and...

    The propeller shaft stuffing boxes are in need of new packing on a boat I recently purchased. I was wondering if anyone has been using the Gore GFO packing material that is manufactured by one of there approved weavers with the 100% GFO fiber (Same company that makes Gortex). This packing is...

    ZF 63A Transmission fluid and filter change.

    I'm not sure this is the correct forum to post this, but it is what is bolted to my Mercruiser 6.2L Engines. No problems with the transmissions but apparently the fluid and filters have not been changed in at least 4 years. I will be doing this in the spring. Most of the fluids listed on the ZF...
