    Another gear lube monitor fitting breakage issue

    Try a 2-3# sledge on it (if room) but make sure that you protect threads. You may be able to thread a nut onto brass threads (Try 2-3) and use a deep well socket to slip over brass flair to where it touches nut. That way, you will be hammering on nuts. Use Lots of break-free lube and soak over...

    Replacing gear lube hose between transom and bell housing

    My bravo hose barbs were brass or bronze, except hoses and plastic/nylon hose clamps. I guess I was lucky. No "e clip," instead a lock nut. Luck again???? Maybe can be re-troed??????

    Replacing gear lube hose between transom and bell housing

    Just use a sharp knife (scripto or razor) and cut vertical slice on hose just enough to bend hose and pull off. I replaced a couple a few months back. I believe hose is 1/4" ID and will be difficult to squeeze cam-latch nylon hose clamps back on but it can be done. The one on transom was the...

    Crank mount pump conversion - any reason NOT to do it

    Lots of new plumbing required for a little bit of gain, if that.

    1992 Mercruiser 4.3 Alpha One Gen II has water in oil after rebuild.

    Is there a chance water is dripping into motor via carb? My opinion, never re-install gaskets after torqueing them. Just my 2 cents. Take out all plugs and retest pressure after squirting inside pistons with oil. Make sure compression tester's release valve doesn't leak. My did one time. Take...

    External Oil Filter hose routing?

    Thanks to all! I am fearful of rubbing and not seeing abrasions too. I may see if splicing a larger hose and inserting the two 1/2" hoses into it for protection is an option. However, tie wrapping on top of bellhousing may be the best and cheapest option. THX!!

    Oh this can't be good. MErcruiser 5.0L loud clicking.

    Water over damn now, but in the future it is best to circulate oil via special tool inserted into distributor hole (I can't remember name of it) . It is turned using drill and circulates oil. Carb may be gumed up. Before tearing down, make sure it is getting plenty of gas from fuel tanks. Mud...

    External Oil Filter hose routing?

    I am restoring an older Sea Ray that has two Chevy V8 stroker motors/Bravo 1s. Covid and heath issues have delayed my progress to the point of frustration. Both motors have external oil filters that attach to risers nearest the sides of the boat. I photo-ed oil filters and attachments but forgot...

    Rebuilding Mercruiser Trim Cylinder/Bravo 1?

    I have rebuilt Alphas in the past but cannot remember exactly where the continuity spring fits inside the the end cap. I downloaded manual 90-863160--1 JUNE 2003 page 5B-3 but photo is not clear, at least to me. I guess I am getting old? Does the spring fit snug inside an o-ring grove and up...

    RADAR with GPS overlay

    I am looking for a RADAR 9-12" screen combination with all the sonar bells and whistles and I also want an accurate GPS overlay so that if I have a RADAR contact, the unit will accurately display contact's GPS coordinates (+-100 feet). A mile range for GPS would be OK but I prefer 2 miles. I...

    Mercrusiser synthetic vs non-synthetic?

    Soon, I will have to change oil in my MC 383s. I have never been a fan of synthetic oils in boats since I normally change oil yearly and don't want the extra expense associated with more expensive synthetic oils. But, then a friend told me that once a motor has used synthetic oil, you can't go...

    Ball valve in fuel pickup tube necessary?

    I am installing fuel tanks now in my 1986 Sea Ray AJ rebuild. I replaced a 140+ gal tank near my engine compartment with two 55 gal tanks located just short of mid-ship. Ancient SRs were notoriously rear-end heavy. SR recognized the error of their ways and replaced the 140+ gal tank with two...

    Mercruiser Gas Tank Pick up Tube?

    This may not be the best or proper forum for my help request. So, if not, please redirect it. I am fitting two aluminum gas tanks into my MC/Searay rebuild, but unfortunately after pressure testing, I noticed one SS NPT fitting (gas tube) had a leak (weird it cracked). I have always been...

    Different Bravo 1 Shafts?

    I suspect that former owner mixed and matched parts that would work on Alphas to Bravos in order to save $$$. Attached are photos of main drive input shafts. One has 4 O-rings, while the other 2 0-rings. The 2 o-ring shaft fit a later style Alpha coupler that had a longer snout with a grease...

    Aligning dual MC ODs (toe-in or out?)

    We finally got both V8s in and have one's shaft aligned. Blame Covid-19 on the delays!!!!!!!! We don't have our Bravo one drives on yet but will soon. We did notice that bellhousings appear to have significant tow out. My cheap manual is not real clear on the correct amount that is OK. Both ODs...
