I have a cruisers rogue with two mercruisers 5.0 engines. IT lacks t power one engine goes flat on torque at 4000 RPM

Mechanic's Assistant: Sometimes things that you think will be really complicated end up being easy to fix. The Marine Mechanic I'm going to connect you with knows all the tricks and shortcuts. Tell me a bit more about what's going on so the Marine Mechanic can help you best.

Fuels system and carbs are new and good. Engines sound perfect. Just a power issue. 800 hours on engines

Mechanic's Assistant: Is there anything else the Marine Mechanic should be aware of?

We are thinking engine advance or restricted exhaust. This one engine not performing.

I have a 1999 Cruisers ROgue. It has twin 305's 8 1998-2001 - 0L015751 THRU 0M599999. Fuel system is good engines sound great. One engine maxes at 4000 rpm it full throttle. Like its chocking. Is the a mechanical advance that could be sticking? Or plugged exhaust? Also how does the engine couple toarque converter?

G​ood morning, my name is ***** ***** am I speaking with? I read what you wrote. DO you have an exact serial number on your engine? Have you ever personally seen the engine make full power under a load?
