    Has anyone upgraded to a 4bbl carb on their Mercruiser 4.3

    Hi all. I am considering changing out my stock 2bbl carb on my 2003 190HP Mercruiser to a 4 barrel EDELBROCK #1409 600 CFM model and highrise manifold. I understand I will likely need to up the pitch as well so will need a new prop. Here is the thing. It seems the advice I get is either that...

    Has any body added Nitrous to their boat?

    I read an article in Boating magazine that explained how easy it is to add a NOS system to any boat. To prove their point they took a family 22 foot bowrider and for a materials cost of just over $700, added 10MPH on top end in one afternoon. They added they had the boat for such a short time...

    Just bought Chaparral now a Maxum is cheaper

    I just bought my 03 Chaparral yesterday now an equivalent year, engine and hours Maxum is for sale for 3k less. Not sure if I should have buyers remorse here or not since I never looked at a Maxum. How does the fit and finish compare to the Chaparral? -Jason

    What did the dealer mean..tap to start?

    Hi all, I just bought 2003 Chaparral with 50 hours on the meter. It has the Mercruiser 190 hp carb engine. The guy I bought it from explained that the dealer told him that at times these Mercs may not start and to tap somewhere on the top of the engine. Apparently this tapping is supposed to...

    considering a 190ls but is it underpowered?

    Hi all, I am considering a very nice 8 year old Monterey 190. It is as nice of shape as any 2007 I have looked at otherwise I would not consider one this old. I don't know much about Monterey's but this one weighs in at a hefty 3300 lbs but has the most basic 4.3 liter carb engine which was...

    Is this too many hours on a boat to consider buying?

    Hi all, I am upgrading my old Bayliner with an outboard to my first boat with an I/O. I am looking at a 4 year old Four Winns 180 with the 4.3 Volvo Penta MPI 225 HP set up used only in fresh water. I understand it is nice but it has 250 hours on the meter. The owner says he has had no...
