We have a 1973, 16 Currituck with a Yamaha 60 4 stroke engine. I would like to also mount a back-up engine. Any suggestions as to size and shaft length? Thx.

---

Did you finally find the Stencil number to determine your exact year?

You need a 20 inch Long shaft bolted right on the transom without any bracket. Whichever side works best for the brand of kicker motor you purchase.

To keep it simple get another 4-stroke so you could run it off the main tank an F4 or F6 both would work fine. They also both come in long shaft.

I asked our boat guy to look again. He finally found the number 15 zeros followed by 32204. What year does that make it? Thx.

---

What's driving your need for a backup motor? To get home in emergencies, or for trolling?

I ask because for the latter, you can equip F60s with the Command Link tach which lets you vary the idle speed for trolling. Also, modern motors like your F60, whether DFI 2 stroke of or 4-stroke, use very little gas when trolling, so a separate motor is not going to save you much there either.

Tim, thx for your help. My interest is for emergencies. Any suggestions on size?

---

You think those are both big enough for a 17' Whaler in the ocean? Thank you

Both would be plenty. But the 6 would give you more speed and control in rough conditions.

No suggestion - I get a TowBoatUS subscription every year instead. My rationale is that a motor light enough to fit on a smaller Whaler isn't necessarily going to get you home in ugly conditions, and if conditions aren't ugly, you've got plenty of time for the tow service to get there.

Whereabouts do you take your boat? How far offshore do you go? We are in Boothbay Harbor, and I don't go far offshore at all - the 15 starts feeling pretty small out there.

15 zeros? No idea.

If it's close to being a 1973 year model, it should also have an HIN tag on the stern of the transom.

II. STRAIGHT YEAR FORMAT
-Late 1972 to 1974-
Example: BWCA60200873
Last 4 characters determine month of manufacture and model year.
3rd and 4th to last characters is the month of manufacture.
01 = January
02 = February
03 = March
04 = April
05 = May
06 = June
07 = July
08 = August (starts next model year)
09 = September
10 = October
11 = November
12 = December
Last two characters designate the year model.
Note: August (08) starts the new model year.
Example of last 4 characters:
0873 = manufactured in August of 1972 as a 1973 model.
0573 = manufactured in May of 1973 as a 1973 model

If it is a 1964 Currituck, then the stencil number of 32204 would be closer.
16' Hull Stencil Numbers (1972 and prior)
1961 ................. 3000 thru 3999
1962 ................. 30000 thru 31499
1963 ................. 31500 thru 31600
1964 ................. 31601 thru 33000
1965 ................. 33001 thru 34399

I run a 9.9hp – 2 stroke Evinrude on the back of mine. I bought the 2 stroke for /to do exactly what Slickityd16t said – run it off the same tank. It moves the boat well, not fast, but well. I use it purely for emergencies and if I need to get out in really shallow water…

---

What size whaler do you have the 9.9 on? Thx

---

Should be a 16 like yours

Here are the Current Engine choices and Weights of the newer motors.

The F8 and F9.9 Yamaha would be a good choice to go along with the Yamaha 60 you already have.

I use my 8hp Evinrude for trolling besides as an emergency backup.

---

I have a 9.9 mercury 2 stroke kicker on my 1999 alert 17 and I can do 6.4 mph with 2 people,30 gallons of gas,and about 100 pounds of gear. I go offshore in Lake Erie and it does give me extra peaca of mind it also gives me 2 starting options,2 steering options,andwith a remote tank for the kicker,2 seperate fuel systems.That being saidmeticulous maintenance of both engines is a must as is common sense.Never take chances and keep a close eye on weather conditions.

Very helpful. Thank you.
