    Could engine coupler need replaced after only 40 hours?

    I replaced my engine coupler in May and now, after only 40 hours on the water the engine rpm's are climbing and speed is falling off again. I did purchase and use the alignment tool. The tool went through the gimbal and into the coupler with no problem. The outdrive slid into place and faced up...

    Standing water in 210WA Sea Pro boat

    I own a 210WA cuddy Sea Pro, 1996 with a inline 4 cyl. mercruiser to power it. I like the boat and it is well built, however when it rains or when the boat is hosed out water gravitates against the bulkhead at the cuddy door and steering station.I then have to mop it out as it will not drain...

    Engine coupler life expectancy???

    I think that I may need to replace my engine coupler. The boat is a 1995 21' Sea-Pro with a 3.0 LX Mercruiser. This engine has about 400 hours on it. Seems like awfull low hours to be having to replace this part. Is this about the average life expectancy? Thanks for the comments. :confused:

    Ouch!!!

    Well,after replacing the exhaust manifold and riser earlier this spring, looks like I need to replace the engine coupler on my 3.0 lx mercruiser. I had hoped that it was the prop,but I scribed a line on the hub and on the prop and after running it the lines were still lined up. So it looks as if...

    Bondo, Trent, everyone... opinion please

    I'm wondering how hard it is to replace coupler in my 3.0 lx mercruiser. In an earlier post I related that the rpms went up and speed decreased while I had the boat out today. No smell of burning rubber but engine temp rose from 140 to 160 and stayed steady, no rise above 160. But I did notice...

    3.0 lx over rev, loses speed....

    I have a 210wa Sea-Pro with a 3.0 lx mercruiser that has just recently developed this problem. I'm ok until I get to 3000 rpm or over. Then it sounds as if the engine comes under strain and the rpms pick up but the boats speed drops off by 8-10 mph. I borrowed a prop from my brother with a 17...

    Sea-Pro 210 WA 1995

    Does anyone else on this forum own a sea-pro? The one I own has a 3.0lx mercruiser in it and I am wondering if anyone else is experiencing some of the "problems" I am. Boat is great on the river as far as a dry, stable ride but it seems underpowered. It also rides bow down when tied to the dock...

    1995 mercruiser 3.0 rattling noise

    Had my sea-pro 210 wa out today, when I opened the throttle above 3000 rpm I noticed a rattling noise coming from the engine. If I slowed down below 3000 it went away.This has never happened before. With the shift in neutral position I can run it up to 4000 and no rattling. Any ideas as to what...
