    3.0, engine oil, breather tube questions

    The 3.0 I had in my old boat had about 800 hrs on it and 145 psi compression and I saw the same amount of blow by and oil as you are seeing. I thought it was an issue but had good compression, wouldnt worry about it.

    Carbed Mercruiser 260 5.7L Missing Above 4000 RPMs

    clogged exhaust is possible if an exhust shutter falls down into the wye pipe. They can make their way into the bellows and restrict exhaust. If you had the drive off recently and looked in the exhust bellows and that was clear look into the tops of the wye pipe. I cant recall if you measured...

    A little give on the shaft?

    When the prop moves in and out look at the nut I bet the nut and shaft is moving with the prop. Its a common thinking this is an issue, has come up many times on this forum

    Prop pitch change

    As mentioned elsewhere you want to prop it to hit in the correct WOT rpm range so more or less for prop testing. The big issue you will have if you dont know it currently is you dont know where to go with your next purchase because you have no baseline. My brother did the same thing because his...

    Prop pitch change

    Really depends on which prop you are thinking of getting and what your current Aluminum prop does in terms of WOT rpm (3500 is way low for wot, assume that is cruise speed or tach is off). If you aregetting to the top of reccomended rpm range for engine AND you buy a basic stainless prop like a...

    2009 Sea Ray 185 4.3 TKS - a few questions.

    Not sure what questions you had. Looks good only only comment would be why use a non marine rated ignition module, generally issue with non marine rated electrics in a boat is spark potential in environment where gas vapors can accumulate i found merc thunderbolt v modules on ebay for around $200

    Changing to stainless steel prop

    What are you looking to improve ? Ive found four blades to improve hole shot stern lift and planning speed. Larger boat like that may like a revolution 4 in 15 or 16” pitch . If you aren’t dead set on stainless might be good to try an aluminum four blade like a michigan vortex 16” . They are...

    Prop Recommendation

    Frist make sure the engine is in good shape tune up wise plugs, cap rotor, fuel filter, carb is clean etc, ti tming checked set. I would think a 19" would do pretty well on that rig. Based on your numbers I dont think the suggestion of a 17 mirage is unsound, as that would get your WOT up...

    5.7L Mercruiser; Engine Running Weird

    measure the fuel pressure and see if you have 4-6 psi at the carb. Possible fuel pump is working intermittently but more likely might be the antisiphon valve on fuel tank outlet. Remove and clean, run it without for a while and see if problem goes away

    Edelbrock 1409 tuning

    You can try leaner and see if that makes it worse . Edlebrock makes a kit with 3 different accelerator pump nozzles. That may be what u need . That cured my bog on my 5.0 with a 1409

    Engine alignment

    I think that looks pretty good. I also had one that was difficult to push the bar in , or more difficult than i would like, i think you end up with so much grease in the coupler when you do this several times. I end up putting the drive on and over the last six years /250 hrs have had no issue...

    Waterproof engine compartment?

    What i noticed on the newer sea rays like 195 and 205 sports with a similar hinged sunpad is a aluminum U channel that runs fore to aft under the seam in the sunpad. I never thought of it till u posted this, but you can cut a hole aft and use this as a gutter. You can see it in the engine...

    Question about a 5.0 volvo penta

    I would just go with new manifolds. Agree with penfield on crack or rot through gasket between manifold and head doesnt have water at that spot. Crack is likely due to lack of winterization. If purchasing this boat that has obviously had a hard overheat and isnt 100% fixed i would pay a price...
