To replace the propeller seal on a 15 HP Mercury outboard, first ensure the engine is off and securely supported. Remove the propeller by loosening the prop nut and sliding the prop off the shaft. Next, take out the old seal from the propeller shaft housing and clean the area. Install the new seal, making sure it fits snugly, then reassemble the propeller and nut, ensuring everything is tightened properly before testing the motor.
The number of splines on a Mercury propeller can vary depending on the specific model and type of motor it is designed for. Generally, most Mercury propellers feature a standard spline count of either 13 or 15 splines. However, it's essential to check the specifications for the exact propeller model and motor combination to ensure compatibility.
For a 1978 70hp Mercury motor with a blue band, a common propeller size is a 10.5 x 13 or 10.5 x 15, depending on your specific performance needs and boat type. It's essential to match the propeller pitch to optimize RPM and speed for your setup. Consider aluminum props for durability and cost-effectiveness or stainless steel for better performance and efficiency. Always consult your motor's manual or a marine specialist for the best recommendations based on your boating conditions.
The circumference at the equator is 15 329 km for the planet Mercury.

A 15 hp Mercury outboard, serial number OG030987, would be a 1994 year model.
The circumference of Mercury at equator is 15 329 km.
The mass of a 15 ml sample of mercury would be approximately 166.5 grams. Mercury has a density of 13.6 grams per milliliter, so by multiplying the volume (15 ml) by the density, you can calculate the mass.
A 15 hp Mercury outboard, serial number OG156835, would be a 1995 year model.
I think about $15
The 1996 model, 15 hp Mercury outboard has a listed dry weight of 75 lbs.
