The Boston Whaler boat did not appear until about c.1960. By that time, I believe the VDO company was already making their black-background dial-face dial-pointer gauges, typically with white lettering in a San-Serif typeface, and with a dial pointer that tapered toward the pointer end. That is what I would describe as a gauge having a classic look.I don't know about the tactile characteristics of those VDO gauges, so I don't know how they feel. But they look to me like a "classic" gauge.
The VDO style gauge was very influential on other marine gauge manufacturers, and I would characterize many of the gauges made today as being in the VDO style or a derivative style. On that basis, I would say that any black-background dial-pointer gauge with white lettering and a white tapered dial pointer would be compatible with a classic Boston Whaler boat in terms of maintaining a classic look.
There are some modern gauges now being made with a very retro style, with white backgrounds and using black type with Serifs. Gauges of this style are much too old for being c.1960 gauges, and I would characterize them as more like c.1930's gauges. I would not include them as suitable for maintaining a classic look on a c.1960 or newer Boston Whaler boat.
Thus, in opinion, there are plenty of options in the market now of new gauges which are suitable for you desire to maintain a classic look (or "feel"). Just get round dial pointer gauges, with black backgrounds, white type in a San-Serif face, and a tapering dial pointer. For a variation you could use red type and dial pointers, but I think that is not quite a classic if looking for that c.1960 VDO gauge style.
