96mirage Posted January 13, 2022 Report Share Posted January 13, 2022 Had this boat going on a couple years and love it. 2005 2 stroke yamaha 90 w/ ~550 hrs. Lost compression in the bottom cylinder, and now considering the rebuild vs. repower dilemma. It seems either way is a sacrifice. Love this boat, and been slowly doing upgrades and updates including: 21 ft stiffy push pole simrad go9 + Florida Marine Tracks New riptide trolling motor w/ remote Full rewire moving blue top batteries up front Read through a few threads like this one, but the bonefisher is a bit different hull as well. Current options seem to be: yamaha 70 yamaha 90 yamaha 90 sho rebuild 2 stroke 90 Yamaha 70 seems to have mixed reviews on overall top end and hole shot, but seems to be quite a bit lighter than the 90 while floating/ poling might be worth the trade off. Anyone repowered the original mirage with a 70 or 90? Everyone love the 2 stroke, and the power to weight is great, but I think I'd like the reliability of a proper repower over time.

Wanaflatsfish Posted January 14, 2022 Report Share Posted January 14, 2022 Where are you located ? For a rebuild...I would take it to John at Maximum Marine in Pompano...he's a 5 star mechanic and is one of the true honest mechanics. Tell him Dino from the MA17 - the Holy Ghost sent ya He loves my ol skiff as I think he had one years ago. Has a great following... He can also sell you a new motor if he can find one...last time I was in his shop (see my post on head gaskets) for my 1995, he had 1/2 dozen rebuilds on his shop benches as he told me he can't find new motors. Great work and enjoy the rebuild/repower decision......personally I feel a good mechanic rebuild is worth the $$ these days...but, it must be performed by a qualified experienced mechanic.....not by a friend who has a cousin in Miami that worked on motors when he was in high school and watches YouTube videos dc 2 Quote Link to comment Share on other sites More sharing options...
polliwog Posted January 21, 2022 Report Share Posted January 21, 2022 i HAVE OWNED A 90 Yamaha 2 STROKE on my BW Montauk. I repowered with the same engine when Yamaha was still making them. It's a classic great engine. I would be careful doing a rebuild due the possibilities of corrosion in the block. I also couldn't put a 4 stroke 90 on the BW because of the weight. I forgot the difference,but it's significant for a small boat. If you handle the extra weight I'd go 4 stroke,you'll be amazed the difference in fuel consumption. My 20 ft LT now has a new 150 4 stroke and I think the consumption is 50% less vs the 150 VMAX 2 stroke. It's also supper quiet. Good luck with what you decide. 1 Quote Link to comment Share on other sites More sharing options...
geeviam Posted January 21, 2022 Report Share Posted January 21, 2022 Call me crazy, but with the added weight you get with a 4-stroke 90 hp outboard, I have seriously thought about checking into this...

polliwog Posted January 22, 2022 Report Share Posted January 22, 2022 That sounds interesting, I'd certainly look into the details of shipping and price. I don't think you want a long shaft for the boat,but I could be wrong. They could have a standard shaft in their inventory. I hear horror stories in the news of getting anything shipped from the far east. I also wonder if a old tech 2 stroke can be imported. I just thought of something . Are there still new 90HP E Techs around? 1 Quote Link to comment Share on other sites More sharing options...

Are there still new 90HP E Techs around? All good questions, and I don't have answers - except that this model is a 20" shaft according to the specs. I can only speak for myself, but at $6,400 for the motor, and if the shipping was reasonable enough (and legal), and the company checked out ok, I might go for it - if I wanted to have that good-ole power-to-weight ratio and reliability that the 2S 90 is famous for.

geeviam Posted January 22, 2022 Report Share Posted January 22, 2022 I'd bet money that the Californians wouldn't allow these motors to enter their ports, so you'd have to pay more to go through the Panama Canal to get to a Florida port with it. 🙄 1 Quote Link to comment Share on other sites More sharing options...

Yes there are new 90 e-tec's still around with full warranty. I happen to be related to a Master factory certified Mechanic for Evinrude so by family law I can't run anything but an Evinrude or Johnson. That and parts are readily available!

MuddyBottomBluz Posted January 24, 2022 Report Share Posted January 24, 2022 Let me clarify my response, there are new E-Tecs to be had, however it is what is left of the remaining stock since they are no longer in production. They will come with full warranty. Quote Link to comment Share on other sites More sharing options...
polliwog Posted January 25, 2022 Report Share Posted January 25, 2022 I think that makes it a easier decision. I hear very good things about the Evinrude Etech engines. I believe they are lighter than the 90 HP Yamaha 4 stroke. That engine will be a lot easier to sell with the boat if you decide at some point.

Yea, corrosion in the block has been suggested as an issue from my most trusted marine mechanic and boat surveyor. It's a great engine, but a bit of a crapshoot since they haven't been imported in over a decade. I've even found a newer crate 2 stroke imported from the islands local but still a pretty high ask price with no warranty. Plenty of leads in south florida (miami) for used ones, but very much a crapshoot on these, or even a rebuilt powerhead. The 90 vmax is about 100lbs heavier which definitely seems like a lot on a boat where the best asset is floating in shallow water.

There's terrible options it seems, but unless i had a cousin, uncle, or hookup, these would be tough to get here I assume. Same kind of goes for the e-tec. I'd prefer to stick with Yamaha and have good local service providers - but there doesn't seem to be an obvious choice at the moment. Appreciate all the feedback and confirmation as I navigate the process and endure the pain of persistent dry land. Quote Link to comment Share on other sites More sharing options...
96mirage Posted April 19, 2022 Author Report Share Posted April 19, 2022 FWIW - The Yamaha 70 was the right choice. I've been out on a dozen or so trips, and over 20 hours fishing it. Caught a bunch of snook, and love the way the skiff runs with it. Lost about 5mph on the top end, but not a huge deal. Cruise is right around 30mph, and still hits 35mph Looking forward to running this '95 for a lot of years to come. 1 Quote Link to comment Share on other sites More sharing options...

What is maximum RPM at WOT (35 mph) with just you driving and a light load? Quote Link to comment Share on other sites More sharing options...
96mirage Posted May 20, 2022 Author Report Share Posted May 20, 2022 Still very happy with the choice 40+ hrs in a few months later. Tried a 15 and a 16 and the 16 is the right choice, but could still use some tuning I think. WOT solo is around 35 w/ full tank on a flat day. This is running 5000 RPM range. Smaller proper I got over 6000, but not where you want to run the engine regularly from best I understand. I might be able to get just a little more top end or hole shot, but overall very happy with the cruise speed ~33.3 at 4500 rpm . Fuel economy is unreal, and no more burning oil. Very happy with the decision overall, and the skiff still floats in nothing rather than adding 100lbs of engine weight for a little more speed and power to a boat that is built to float skinny. I might look at a 4 blade for a little better hole shot, but not a lot of need to get on a plane in 18" of water most the time, and will probably be happier enjoying a flat that prop testing. If I do, I will report back. 1 Quote Link to comment Share on other sites More sharing options...

Sell or trash that old bass boat and trailer. Quote Link to comment Share on other sites More sharing options...
