    Mercruiser 5.0 TKS vs 4.3 MPI

    I have a sea ray 200 sport with a 5.0 carbed. So that boat will do great with a 5.0 TKS. This is my second sea ray and both have held up really well. I personally prefer the carb as I do all my own work and while I know I will have a few (2) carb rebuilds over the 15 years I plan to keep this...

    Slow Trim Up on 3.0 Mercruiser Alpha 1 Gen 2?

    I used a turkey baster to suck the reservoir empty, refilled it with fresh fluid, ran the drive up and down three or four times, and repeated whole process several times until I had flushed it completely. I found a gallon of the equivalent hydraulic oil at the auto parts store for like $15. I...

    Where to pick up power for electric choke?

    The purple wire to the ignition is where mercruiser picks up power to the electric chokes. i think the adapter is factory. you can plug your serial number in on some parts sites and the parts breakdown drawings show an adapter between the manifold and carb that look like spread bore adapters.

    Tuliped valve causes

    Yeah better off being a tad under propped vs over propped, especially if you tow. if you yank the heads and have tuliped valves would think it’s wise to replace them all especially on a SBC Where parts are relatively cheap

    Building a '93 Caravelle 1750 Classic Bowrider

    Yes only use prior to start up and theoretically at low speed. You’ll find factory vents will blow air into engine compartment when moving, exhaust will suck off the bottom where vapors heavier than air will accumulate. This is not not only for fuel vapors but engine compartment cooling as well.

    980 hours on engines - compression test

    My advice might not be as much fun but ... leave them alone . If you’re only getting 25-40 hrs a year ( I do the same in upstate NY) They will probably be fine when u do go to upgrade. Whats your oil pressure at hot idle and WOT? Certainly whoever you sell your boat to will be getting a very...

    Carb Rebuild Kit

    No I had to SWAG it as the brass one does Not have the mark on the side that u use for float level. I think the Brass float is from an older Rochester 2 bbl that was the forerunner of the Mercarb. You maybe able to find a float level off one of those instruction kits. they may be on Mikes website.

    Best Carb Rebuild kits.

    I have had really good experiences with mikes. I think his mercarb kits come with both styles of accelerator pumps and spring loaded or non spring loaded needle and seat. They also sell floats in brass and idle mixture screws if yours is balled up . Also helpful with phone and email tech support

    Twin V catamaran set up

    My brother has a early 2000s 17 ft Twin V center console with a 50 hp Yamaha 4 stroke. Apparently it was originally sold with a 35 hp and the original owners repowered around 2008 with the 50 (hull is rated for 60hp) . Issue is when wide open it doesn't seem to go as fast as he'd like and has a...
