New Merc 30 hp problems

2 posts in this topic

I have a 2003 30 hp mercury 4 stroke EFI and have a couple of questions. It is on a Lund Rebel 1650 and runs great for the most part. The problems that I am having are getting the motor to plane out and getting it to idle lower. I am not able to troll below 2.5 to 3 mph forward and 1.5 to 2 back trolling. It also sounds like the motor is bogging down when I try to run at full throttle. Does anyone know what would be restricting the motor? It idles well and starts and runs great.

Also I have heard the rumors that this can be upgraded to the 40 horse as it has the same block and displacement. Does anyone know if this is true and if so, is it worth the upgrade.

It sounds to me like you have too high pitch prop on your motor (which is probably what came with the motor when the dealer got it). Take a look at your prop - which might require removal, for a 2-digit number before the P on the prop. It might be in the hub of the prop (on the outside of the prop), on the backside of one of the blades, or stamped on the hub, which will require removing the prop.

With respect to idle, I presume you mean that it moves to fast in idle, not that the motor seems to idle too high, correct?

    • Glad Lavine is gone! Added nothing but slam dunks to the team. I've been out of town for the past week, so I was very delighted to hear about this trade today.
    • Not unless they ban the toothpick crossbow here too. Takes those beetles out clean.   
    • That's called seasoning. Two years ago I took a trip to Germany and we spent a few days in the black forest where I got to see some authentic old world smoke houses dating back to the 1500's and the amount of buildup on the walls, hooks, poles etc is part of what gives their hams,bacon and sausage their flavor. They use juniper wood for smoking. Absolutely delicious.  But yeah, foil, Pam and other things can help. You can also use a power washer to clean them.
    •   "We have found they do not like limburger cheese, hot dogs, or Makers Mark bourbon.  I am thankful for that."   Thanks for making my nite.  
    • Also woodpeckers beat on stuff to mark their territory.   I am pretty sure that there aren't any bugs on my metal downspouts.
    • You will often discover that birds are picking very small insects from decks and other woodwork around your house;  they do the same with trees and any other structure that might hold the bugs. We see them often on our decks and they usually pick a little bit and then move on,  perhaps just checking to see if there is anything edible there. These rascals also love hummingbird or oriole nectar, sunflower seeds and of course suet in winter. We have discovered  many species that will head straight for the nectar for orioles or hummingbirds and also plunge their beaks eagerly into the grape jam bowls orioles love. Birds will eat a greater variety than you might think. We have found they do not like limburger cheese, hot dogs, or Makers Mark bourbon.  I am thankful for that.
    • And pretty soon there'll be little chinese restaurants springing up everywhere...there goes the neighborhood. 
    • I use the ball of aluminum foil, too. Works well.
    • lay them in the grass over night and wipe off in the morning.  the dew soaks in if it's moist out.  other wise lay them out and place wet towels over them for awhile..
