Remember these Volvos do not have flappers at the top of the Y pipe as Mercs do and OMCs did. In fact the Volvo SX is ad adapted OMC Cobra design that had flappers just like Merc. Volvo felt they didn’t help so they removed them. Mine has had them all this time and I never had a hydro lock. I...
As long as the boat is 100% winterized I’d be more focused on the trailer and condition of the tires, bearings brakes and springs as well as the winch & tie downs. Make sure to have a spare & tools to change it (jack and correct size lug wrench). Don’t assume your tow vehicle stuff will fit! Lug...
In the last few years I started using Sierra PG antifreeze mixed 50/50 with water because it’s about half the cost of -100 and still gives freeze protection down to -30 or so. I use a refractometer to measure it which is more accurate than the eye dropper style hydrometer which they do sell for...
You set the dwell meter setting on the 6 cyl setting and the positive lead from the meter gets hooked up to the coil negative terminal the negative lead from the meter gets hooked up to the battery negative or engine ground. Crank the engine over & read the meter. Point gap & dwell are inversely...
Those prices are high for 15+ year old boats, keep in mind that boats have a fixed service life, and also, certain parts for I/O drive systems start to become NLA after about that time.
if any of them have wood in the structure, you have to be really careful, because at that age rot can be a...
You know I’ve never gotten much smoke any year I’ve done mine just a bit….I think stalling it is important because if it doesn’t stall most of the oil will burn off instead of leaving a coating
So Ted you’ll become the go to guy for new Mercruiser tech! Im thinking that to winterize these engines you’ll need the remote tank for the fogging fuel mix and a winterizing tank which can be used with closed cooling. I have one that I used as a brake flusher but will use for winterizing when I...
So when you re-start in the spring, let the engine burn off the fogging oil, it might smoke and run a little rough, let it run about 20 min on the water hose and then put in a new set of spark plugs and see how it runs then. I will often put an old set in for fogging then put the clean set back...
not worth re-doing it now because it is fogged, main concern is if the engine runs OK in spring, due to possible fouling of sensors. So I'd leave it be for now, just be aware of this in spring.
I still don't think he was right. Both Mercruiser & Volvo tell you to do the same thing basically, just different mixes of 2 stroke oil to gas, Merc says use 10% Volvo says to use 2%. In fact what you could do to make it REALLY easy is figure out how much gas the fuel filter holds....fill it and...
Congrats and beautiful boat Ted! I knew the weather would be good so nice easy trip in a boat that size. Excellent!
PS just winterized my brother's 2020 Chapparal with the Merc 4.5 (raw water cooled) nice easy remote oil filter mount, easy water drain works well, filled it up with -100 marine...
Once and only once I went out during a small craft advisory winds were approx 20 mph, got green water over the windshield, my son who was about 7 at the time thought it was great fun, lol.
I'd try to get a hold of a VP manual ASAP, for example Mercruiser tells you to mix a 10% mix of TCW-III oil (2qts) into a 6 gallon outboard tank with 5 gallons of gas and stabil to fog their EFI engines, even the latest ones in use. 50:1 is less strong than that (50:1 is only 2% so I can't see...
I use the Windy app and also the Univ of Conn weather buoys that are across LI Sound, also I look out from my back porch if I see whitecaps on the bay I stay lol!
Anything more than 10-15 mph is not pleasant in a small boat.
Well I have one of these:
so it's hard to say but if you have a throttle body for either TBI or port fuel injection, and you have sensors in the throttle body, it would seem that the fogging oil could foul those sensors. What does Volvo Penta say?
They are just parts pushers with no knowledge!
Dwell must be correct for the primary & secondary ignition system to develop the 25,000 bolts to fire the plugs.
I have the same engine, owned it about 20 years now and it’s always been a reliable starter as long as the ignition is maintained. The Prestolite distributor is very simple to work on. You need a tach/dwell meter and a timing light to get this working reliably. The dwell must be at least close...
that's about the ONLY way I'd ever get another old boat and even then, unless its an outboard and you can afford to repower with new, if its an I/O even Mercruiser discontinues old parts. Something to consider.
other than those situations I stick to what I said, USED not USED UP. Meaning, 5...
