2008 Searay Amberjack with twin 5.7’s Bravo3 drives DTS shifter

Definitely fuel. Had a similar issue with my boat turned out I had a bad injector #5 seems to put the boat in a lymph mode. Have merc mechanic run diagnostics and I’m pretty sure it will be an injector

The cabin keys are always left on while I’m out and about in the water. I moly turn them off at the end of the day. When we went to start the engines back up for like the 5 th time the port did not start and I went ahead and turned the key off them back on and that’s when I noticed no short beep...

The beep is only when I turn the keys in the cabin. Then at the helm I push the start button and they start. Starboard good port just cranks. In the morning I had the same problem and the mechanic came and just pushed in the plugs on the ecm and I got the beep and the engine started fine but...

I have a 2008 Searay Amberjack with twin merc 5.7’s . Boat was running great all day was stop and go throughout the day, but on my last startup to head in for the day when I turned the engine keys on in the cabin I hear both the fuel pumps engage and a quick short beep on my starboard key turn...

On a different note I have decided to repower my boat. Looking to upgrade from my 5.0 Mercruisers to 5.7 350......any recommendations on where to buy them from at a good price. Also being that I spent almost 6K on original OEM manifolds and risers.....should I sell them seperately? Any...

Yes the fuel cool system was replaced but on the starboard engine. Both fuel filters were also changed last year.

Thank you both for the responses. The starboard engine does not have any alarms. It is the port engine showing the fault on Injector #5. Both engines in neutral rev over 4500rpms but when engaged the boat does not exceed 2900 RPMS....not enough power to get it to plane.

Had a Mercruiser tech put the engines on the computer. Turns out that my fault is Injector #5.......would 1 bad injector cause the boat to lose that much power and not allow me to get on plane?

Good evening wondering if anyone on the forum can help me with my 2008 Searay Amberjack with Twin 5.0 Mercruisers. The last couple of times out on the boat I cannot get past 2800-2900 RPM's …….8-12knots......not allowing me to plane and reach my cruising or faster speeds. 2- warnings on my smart...

Thanks for all the feedback. Although painful $$ I am gonna rebuild. Love the boat but gonna fix it....sell and go to outboards. Spent a fortune on these engines and just want to get rid of it.

The exhaust flapper was intact. There was rust build up in the manifold and where the exhaust riser gasket goes. My concern was also traces of gas in the oil. I started to pump out the oil and spent 15minutes pumping out pure water with signs of fuel in the water. Got so discouraged and after...

Have Twin 2008 260HP Mercruiser with Bravo III was out 20miles, calm seas I stopped the engines for a few minutes then restarted. My port engine started but starboard was struggling to turn over. Keep trying and the starter locked up. Boat was running fine to this point. No overheating or funny...
