My old Honda 9.9 has finally succumbed to 23 years of very salty water. I would like to replace it with a new Honda 4 stroke engine and need to know what kind to buy.

What size shaft do I buy?

Should I get a 9.9 or an 8.0?

I'm thinking that I want to get one with electric start, and electric tilt, but have had no experience with either and would appreciate any feedback.

Also, I really need to replace my old motor mount bracket with one that has a strong enough spring to actually enable my wife to lift the engine with minimal effort; any input you have as far as brands / models, installation, etc. would be helpful.

Thanks in advance.

What I'd get.. (just my 2cts)

Honda 8hp high torque model, EXTRA-long shaft.
Second choice... Yamaha. (I've heard that Yamaha is better supported in Mexico.. if that's an issue for you)

Garhauer stainless engine mount. (www.garhauer.com) bedded with 3M 4200 compound. 'starboard', 'hi-moly' or stainless backing plates where the mounting bolts come through, also bedded with 4200. Bolts sealed with 3M 101 compound as they are put in place.

For fasteners.. 316 stainless bolts, fender washers and nylon locking nuts.

Currently maintaining two holes in the water...'77 Venture 23 and new to the family,
'78 Catalina 25

My recommendation is the Power Thrust 8 hp extra-long shaft (27.7"). The new 8 is the same engine as the 9.9, but slightly limited in RPMs. I have never come close to opening it up, so the higher RPMs have no meaning to me. The Power Thrust model has a larger diameter, lower pitch prop that gives you much more starting and stopping power, which is especially useful around a dock or trailer. I think that model only comes with electric start--very nice to have. I don't have the new electric tilt and can't comment on it except that it'll add some weight to an already heavy engine (108 lbs without it).

Yamaha also makes a very nice high-thrust 4-stroke, but the Honda has several advantages:
- pull starter as backup
- double the alternator output
- almost 3" longer shaft

The new Mercury/Nissan/Tohatsu 4-stroke is heavier, shorter, and does not offer a high-thrust configuration that I know of.

The updated Garhauer bracket (like the original stainless tubing unit) may be the best option out there--I think somebody on this board has one. It has a steel and starboard mounting board, beefed up parts, and an additional spring, so we'll see if anyone can comment on its ability to lift a 100+ lb. motor. Catalina Direct sells them, or you can go directly to garhauermarine.com. You want at least 11" of vertical travel for an extra-long shaft. My Fulton 1810 has that and is built like a bridge, but it must be blocked at least 3" away from the transom for clearance.

I put a 1/2" Starboard plate between the bracket and the transom, and a smaller piece inside as a backer.

Glad to hear your Honda did so well--I'll look forward to the same service!

I'd do the Honda 8hp 4 stroke with XL shaft. It is the same motor as their 9.9hp but with limited rpm. Same block, but plenty for a 25 ft sailboat. I have the elec. start, and it starts every time and easily. It is Honda quiet too. YOu can run full bore and still talk. Also, it is several pounds lighter than the others I considered. I think it's around 100 lbs, and most others were around 120lbs. This makes a huge difference for balancing your boat.
