    Oil pressue ??

    So I fired up both the new engines on the ground today....4.3 vortec (1998)... After dialing in for a bit I was very pleased...... Only one question I have is that one engine has about 40 plus psi at idle, and the other is at 30 psi at idle....once revved up it goes right up to 40 or more... is...

    Upgrade to closed cooling?

    Re-powering both engines..... 4.3 Vortec 4 barrel... Alpha 1 gen 2.... My question is it worth doing a closed cooling upgrade considering I am installing new manifolds, risers, and new engines? Not sure if the outdrives have an effect on closed cooling.... Never had closed cooling, but if I am...

    Props vs Barnacles?

    So I have been fighting more than one issue evidently.. Got my port motor running finally, and went out this morning. Ran fine except it wouldn't rev over 3800. Stbd revved to 4200. So I decided to check props..... Trailered up the alpha's and I found moderate growth of barnacles on both...

    Water leaking into bilge???

    So I have had an annoying problem all year... Today I decided to try to figure out what the reason that I have 1.5 inches of water in my bilge.... I know rain etc. but I vacuumed out the water and started port engine, and I can see water trickling down the back of the transom... I cannot really...

    Timing marks on 4.3 vortec ??

    So I wanted to check the timing on my port engine to verify that it is indeed set correctly.... I look at the front cover, and see that there is one "tab" with a notch in it. I assume that this is the mark that is used to determine the timing. I look at the harmonic balancer and see only on...

    4.3 cut out... won't stay running?

    So I was out today to try to figure out if I have an issue.... I was out last week and I seemed to loose rpm, and speed (about 200 rpm, and 2 mph). It was rough out, and I had a load on, so I thought that may be the issue. Fast forward.... I went out, and found that she was still a bit...

    Lost 200 rpm?

    I am curious if an extra 400 pounds and nasty seas will translate into a loss of about 200 rpm and about 2mph? I was out in a pretty nasty wind... probably 3 footers or more..... It took a bit longer to get on plane, and I needed to pin the throttles (which I normally don't have to do) to get...

    4.3 oil leak... possible front seal

    Went out yesterday for a nice long ride... opened hatch and saw a bit of oil on the bilge floor under port motor... looks to be slinging from the harmonic balancer. Looks like plenty of access, but I am curious if the seal is the same as automotive? Where could I get the part number from? I...

    4.3 spin on water separator

    I am going to change the water separators on the 4.3's. Do I need to fill them with gas in order to assist with the priming of the fuel system? I don't want to burn out a starter trying to fill them.....

    2brl-4brl ..4.3 l?

    Has anyone done the 2 brl -4brl conversion on. 4.3? Not really concerned with great power gains, but just want her to run great. My 2 brl's seem to load up overnight and take a while to clear out when first started. Carbs were rebuilt last year. Not a fan of the Mercarb 2 brl. Any advice is...

    Temp ? On 4.3's

    Fired up both today. No problem firing..... One potential issue ... the port engine temp gauge went up to about 180, then down to 165 or so (when the thermostat opened I assume).... She just kept cycling from 165 to about 180..... This is similar to last year, but I don't remember it going to...
