Author Topic:   repower 1998 Outrage

I am in the process of repowering my 1998 Outrage and would appreciate any first hand advise. I am interested in the Yamaha 200/225 4 Stroke, but would consider twins even with added cost and weight. The engine weight capacity is 700 lbs/ 300HP, but would like to stay around 600lbs. I fish mostly in the Gulf of Mexico out to 20 -30 miles and have a 125 gallon fuel capacity. Appreciate any comments.

First we need to know which size boat you have. Outrages came in several sizes that could be powered by a 225HP outboard motor. I am guessing yours is a 21 or 23 foot because my 20 foot 1998 Outrage is only rated for 225HP. Last year we put a 225HP Yamaha 4 stroke to replace the origonal 200HP Yamaha 2 stroke. The four stroke motors have many advantages and a few disadvantages.

Extremely Quiet
Fuel Efficient
Run at idle all day-no trolling motor needed
No oil tank to keep replacing oil
Did I say Quiet

Heavy (subtract the weight of a trolling motor and they look better)
Less power than expected (our F225HP=old 2 stroke 200HP in performace)
Yamaha has rated the F225HP motor optimistically

Check out the Yamaha 300HP HPDI or the Suzuki F250 also Mercury has some new models to consider.

all the best,

Boxers, thanks for the info. My Outrage is a 21', which I am told by Whaler the hull is still available for commercial/law enforcement only. The added engine weight is my main concern, but with the 4 stroke I will forgo the kicker. Any issues with the Yam 225 4 stroke? Did you give the Honda 4 strokes a look? I had a 98' 200HP EFI Merc that seized 2 cylinders out of nowhere so I am less inclined to look at Mercs again, plus I prefer the Yamaha controls. Thanks again.

Rusty, have you determined the cause of the seized pistons event!? Sounds like a fuel delivery problem to me (just a hunch, mind you) and if so the problem could be in the boat's fuel tank (s),lines, primer ball, shut off valve, check valve at tank if there is one (check it out), and any filters and fittings. Good insurance anyway to clean tank (s) and all fuel related components and give the new engine a break (no pun intended!). Good luck! Clark.. Spruce Creek Navy

I've got a pair of 225 4 stroke Mercury/Yamaha. The only current issue is a bushing in the throttle linkage which be being replaced as a recall. You might consider going with the Mercury engine which will allow you to reuse your current Gauges and throttle. If you have Sea Star hydraulic steering you may need to change the steering cylinder. You're looking at about 630 Lbs with a 30 inch shaft and ss prop. See if you can find a similar boat a go for a ride.

Clark's post points out one thing I like about 4 strokes. You don't need to count on fuel to get lube to the engine. (I know DFI doesn't either) I like my 2.32 gal per minute oil flow at 1000 RPM.

Regarding any issue from Yamaha 225-HP 4-strokes: I have heard that even in large mixed populations (i.e., normal and counter rotating) that have been kept together in dark warehouses that no offspring have been reported.

I had to read your post twice, then think a little bit, read it a third time and then I got it...pretty funny. It's getting late.

I wondered where kickers come from?


As for the Honda 225 I did consider it but the dealer network is minimal in southeast coast of NC. There have been a few comparison reports between the motors and the Yamaha was picked by a narrow margin over the Honda.

The paint on the Yamaha seems to be a bit better suited for salt water use as it has held up better than the paint on my Honda. Honda also uses chrome bolts on the engine casings which have been shown to rust in a salt water environment.

A fourstroke motor should be of no concern if you choose to go with a large single. Our boat is only a 20 outrage and the static trim keeps the scuppers well above the waterline despite the 600lb motor on back. We did add 12 X 12 trim tabs which probably helps the overall cruising and holeshot performance.

If it was me I would put the max HP on your 1998 OR-21 so that would mean 2X150HP or 300HP single. If the boat can handle 700lbs on the transom you have many good options.
