    Which hull brands to avoid

    One thing that is great about Aluminium Hulls is that they bounce and dent when hitting Rocks that would Shred Fiberglass Hulls

    1962 Evinrude 18hp Compatibility with 1969 Evinrude 18hp

    I used to think that, but the 64 5 1/2, and later 6hp still had Bushings for Crankshaft Bearings. OMC did spec 50:1 for them though

    When you put the Carbs back on did you do a Link and Sync? Are both carbs fully closed at Idle, they are supposed to be, and they are supposed to remain closed until the timing advances to a certain Value(varies with engine model). Do you have the Proper OEM Service Manual?

    Getting new prop, couple questions

    Yes they were, and the QC of their Product is Abysmal, Putting 2 different designs of Blades, doesn't result in an Increase, but rather a Decrease in designs performance. But some people will lap up the Marketing Hype

    Getting new prop, couple questions

    Solas, never owned one, and my experience is limited to being in my cousins Boat that had one. Seemed to perform okay, and looked very similar to an OEM prop. But Solas offers more than one Line... My dealer sold another 3rd Party Brand, and I was not impressed with the QC. I had opened up...

    Getting new prop, couple questions

    A change in Diameter can affect loading, however, so does Blade Shape, Blade Area, Rake, and Cupping, so it isn't as cut and dry as a lot of people may think

    Getting new prop, couple questions

    Temperature and Air Density. The Air in the Spring and Fall is cooler and more Dense, thereby the Engine can produce more power. So if proppeed in the Spring or Autumn, the Owner is wondering why his motor in the Hot Summer isn't getting the Rpms it did in the Spring. Mercury even mentions this...

    Getting new prop, couple questions

    You mention Rpms are low. Is this a new thing, as you also mention what might be misfires? Keep in mid that propping this time of Year usually results in a prop that is too high in Pitch during the summer. Unless you are south of the Equator. I believe your engines WOT Rpm Range is 5000-5500...

    16ft Glasspar w/65hp 2 stroke

    Depends on how the engine Wiring is. Some Wiring Diagrams show the Tach lead going to the Ignition System, others, even for the same HP, show it going to the Charging System. Changing the # of blade has no hard and fast rules regarding pitch adjustment. The 2 Blade Props Mercury used to make...

    That is exactly what Glastron is an Entry Level, maybe even subentry Level

    Glastron is Garbage, and they certainly DO NOT Honour their Warranty

    If you use an Automotive tach on the Ignition, you would have to set it for 8 cylinders.

    Compatibility, as well as a Sale. In the late 60s early 70s Merc moved from using the Ignition System for the Tach Signal, to the Alternator. For me, I find setting the Tach for # of Cylinders far Easier, than for an Alternator, as I can count Cylinders.

    16ft Glasspar w/65hp 2 stroke

    A 1969 650 would have a WOT Rpm range of 4800 - 5300. I find 6500 with a 17" prop on your boat a little high, either you have a lot of Slippage, or the Tach is way off. As mentioned, Mercury did offer a lot of 2 Blade Props for their Engines in the 60s. The 2 Blade Props had a larger Diameter...

    Outboard life expectancy

    Water Cooled Engines tend to run a lot Cooler than Air Cooled Engines, and that is why the TCW Oils were developed. TCW in an Air Cooled engine usually isn't a Good Choice. I like smoky Oils as they help keep the Skeeters away.

    TCW smells different than Oils for Air Cooled engines
