Professional tools for marine outboard lower unit teardown and repair

WHAT OUR CUSTOMERS SAY

Bill

"This puller is solid, but I still managed to break off a bolt until I adjusted my procedure for pulling that stubborn flywheel. Also, the management was nice enough to send me a second set of bolts. Great puller indeed."

Bill

"Fits perfectly due to having 2 sets of pins included. NOW, if repair parts would arrive I could get the job done. Any chance Marine Tech could start selling Yami parts too? Your tool arrived in 2-3 days all the way across the country to Oregon. Can't wait to actually use it. Thanks. Bill"

Jim P

"Used this to service the trim/tilt cylinders on my 1999 OX66 Yamaha. Impressively well made tool. The trim cylinder caps came right off using this tool after 25 years of being together."

Ben Ro

"I play in a horse shoe league and have pits in the back yard. I have several professional sets of horseshoes. These are freaking awesome, and exceptionally well made! Looks, feel and weight these are easily the best I have come across. Laser etching for the Marine Tech logo looks sick! A good pair of professional shoes (2) will run you $50-100 range. The price for two pairs of these (4) plus the bag and the stainless screw steaks is awesome. My kit did come with 2 sets of screw stakes as well so reviewer Shawn's order might have just had a shipping issue or Marine Tech listened to the feedback. Marine tech also sent me some cool SWAG with the order. Extremely Pleased! "
