    Hull is pretty clean and props have had propspeed treatment

    Volvo TAMD40B won't rev past 3000 - props or worse?

    Thanks STB. I appreciate the detailed response and the wisdom shared. My first thought beyond props was whether the throttle cables were adjusted short (by accident or design). Also saw a graph showing different injector curve settings and wondered if it could be that. There were rumours around...

    Volvo TAMD40B won't rev past 3000 - props or worse?

    Hi Folks. I'm looking at purchasing a planning type 39' launch with 2x of these engines. These ones however are only doing 3050 or so rpm flat out (about 14knts). They're supposed to rev to about 3600 which is where they make their max power (165hp or there abouts). Boat is shaft drive. Other...

    Buying Markline 1100 - shafts or SD?

    Thanks Folks. Appreciate the solid advice. My ideal would now be the Markline 1100 on shafts fitted with the 200hp volvos. The one I'm looking at has 165 volvos but I'm certainly not going to discount it based on that. It's a very well cared for and equipped boat. Will have the opportunity to...

    Buying Markline 1100 - shafts or SD?

    Hi Bruce. A family member ordered a brand new Bavaria from the factory a year or 2 ago. Around 40ft+ Very little change from $700k AUD and it came from the factory with SDs. Re your link. That's exactly where the engines are fitted originally on the SD equipped boats. As aft as can be really...

    Buying Markline 1100 - shafts or SD?

    Thanks Darkside, much appreciated. Aside from more speed and abit less draft what other advantages would 35 year old stern legs offer over similarly aged shafts? Maybe better fuel efficiency? If I'm just weighing up abit more speed against a lot more maintenance (cost) it would seem that the...

    Buying Markline 1100 - shafts or SD?

    It does have tabs which I'm sure should would help. Unfortunately no advert as it's a private sale. I approached the owners directly.

    Buying Markline 1100 - shafts or SD?

    Thanks and I take your point. I'm definitely the novice here so I'm taking it all on board. Just notice when I walk through any pleasure boat marina here a HUGE portion of the power boat are running stern drives. They are incredibly common. Why would such a flawed and troublesome technology be...

    Buying Markline 1100 - shafts or SD?

    Thanks Bruce. Much appreciated. The 165 is the hp rating. Apparently they came with 165hp AQAD40 engines or 200hp AQAD41 versions. I'm not too interested in speed but just wonder whether driving a planing Hull at only ever 13 kn or so is the best way to go?

We've found 2x for sale one on shafts & the other running stern legs, Both powered by 165hp Volvos that are well maintained. The boat on shafts cruises at...
