    During a maintenance and shift cable repair on our 1996 Sea Ray 280 BR with twin 5.7L Mercruisers and Alpha One drives, it was discovered that most likely when the boat was built, the clamp on the transom water fitting had squished the fitting reducing the volume of water supplied to the starboard engine. This explains the mystery of this engine running at a higher temperature than the port engine. The mechanic says the only way to replace the fitting which is plastic is to pull the engine. Any thoughts on whether there is a way to replace the fitting without pulling the engine? Also, any thoughts on whether I should contact Sea Ray since it appears it was done when the boat was assembled?

    no need to remove the motor but the drive and gimbal need to be removed, the hose inside the boat and the retaining nut and plate. Then wiggle/push/turn the inlet pipe out

    The drive and gimbal are already out but the space seems limited in the engine area. This is a twin engine situation, do you still think it’s possible?

    The twin engine may not be the issue. Typically you have to lay across the top of the motor and reach your hands down to remove the small bolts on the inlet tube.

    Every boat is different, I can do his on my boat in less than an hour.

    The water tube is out, only the riser off the exhaust manifold needed to be removed. Still need to get the replacement part and install it.
